Version 0.4.3 (the real one): fix Gentoo ip config failures and crashes

This version fixes problems with locating the 'ip' command on Gentoo and possibly other Linux systems, and a problem that could cause a crash if EthernetTap was unable to locate one of the commands it invokes to configure IP information on tap devices. The code also now builds on Windows. It doesn't run yet, but it's a step. Windows port is in full swing. Finally, the multicast rate limit defaults were raised a little. More testing is needed here, and real world measurments.

 **FAQ**

 **Q:** What can I do with this?  
-**A:** For starters, try opening iTunes if you have it installed. If others are also online and sharing their collections, you might see them. If you have any games that run over a LAN (except those that require IPX), try those. What else can you think of to do on a completely flat, open network? Collaborative software development? Remote debugging? Transferring files using simple drive shares? Sharing your desktop printer to someone on another continent? Use your imagination.

Remote debugging? Transferring files using simple drive shares? Sharing your desktop printer to someone on another continent? Use your imagination.

 **Q:** Why do I get an IP address in the 27.0.0.0 or 28.0.0.0 range? And why does a lookup claim these addresses belong to the U.S. Department of Defense?  
-**A:** Short answer: because IPv4 needs to die. Long answer: the Earth network assigns IPv4 IPs from these ranges. They do in fact belong to the DOD, but they are *not* routed to the open Internet. The DOD owns them but uses them internally for private networks. As a result, there is nothing *technically* wrong with "bogarting" these for our own private network. It's considered bad practice, but if you want a private address space in IPv4 that is unlikely to overlap other private address spaces (like 10/8 and 192.168/16), it's the only way. [Cellular carriers](http://www.androidcentral.com/sprint-internet-dept-defense-and-you)  and [cable companies](http://www.dslreports/forum/r25679029-Why-is-my-first-hop-to-a-DoD-assigned-IP-address-) frequently do the same thing.

 **Q:** Is IPv6 supported?  
 **A:** Yes. IPv6 link-local addresses (those in the fe80::/10 block) are auto-assigned and should work fine. No other IPv6 addresses are assigned *yet*, but there are plans to do interesting things in this area in the future.

+**Q:** I don't want a giant Ethernet party line. Can I leave it and create private LANs instead?  
+**A:** Yes, soon. A GUI to configure such things is in development. But for now there's only Earth.
+
 **Q:** Are you going to charge for this?  
-**A:** Public networks will remain free, but we intend to charge for private virtual LANs. ZeroTier has other ideas too, but they're top secret for the moment.
+**A:** Public virtual LANs will remain free. We intend to charge for private networks in some way, but the exact model is TBD. Other cloud-supported paid features are also TBD.

 **Q:** What's a supernode?  
 **A:** Supernodes are nodes run by ZeroTier Networks that orindary users use to find one another and communicate until/unless they can perform NAT traversal and connect directly. They run the exact same software as everyone else. The only thing that really makes a supernode special is that it's designated as such.

 **Q:** Can I run a supernode?  
 **A:** No, not at the moment, and there would be no benefit to doing so.

+**Q:** Will my local firewall rules apply to ZeroTier One traffic?  
+**A:** ZeroTier creates a virtual Ethernet tap device (zt# on Mac and Linux) that emulates a wired Ethernet port. If your firewall applies to *all* network ports, it will filter traffic through this port as well. If it applies only to the primary interface, it may not. See your OS's firewall documentation, as different OSes and flavors thereof have slightly different configurations in this regard.
+
 **Q:** Can you see my traffic? What about other users? Can you sniff the LAN?  
 **A:** No. All unicast (direct computer to computer) traffic is encrypted end-to-end (even if it's being relayed), and the ZeroTier virtual LAN behaves like a LAN with a secure enterprise-grade switch that does not allow unicast conversations to be sniffed. Multicast and broadcast traffic will of course be seen by many recipients, but that's the idea.

-**Q:** You say "almost unlimited size." Isn't multicast and broadcast traffic eventually going to be too much? What happens then?  
-**A:** ZeroTier One uses an algorithm called *implicit social switching*. The overall maximum number of recipients for a multicast is limited, so if there are too many listeners to a given multicast address then obviously not everyone will receive every message. So who does? Social switching causes multicasts to propagate in the direction of peers to whom you have recently communicated. As a result, multicasts tend to propagate along lines of association. The people most likely to get your service announcements are those with whom you frequently connect.
+**Q:** What about privacy? Does this hide my location on the network?  
+**A:** ZeroTier is not a connection anonymizer. Other than encryption, it doesn't do anything special to hide your identity or network location. If you want strong privacy protection there are already very advanced tools like [Tor](https://www.torproject.org) for that, and this isn't trying to duplicate their functionality. At the same time, ZT does not do anything special to harm your privacy either. It's not spyware or snoop-ware.

-**Q:** I don't see broadcasts.  
-**A:** At the moment only Ethernet multicast is propagated, not broadcast (ff:ff:ff:ff:ff:ff). This may change in the future. IPv4 ARP uses broadcast but is handled by special code that subscribes to a multicast group using the broadcast address combined with the IPv4 address to make it address-specific. See comments in MulticastGroup.hpp for deeper technical details.
+**Q:** Is this designed to replace IP, BGP, IPv6, routers, etc.?  
+**A:** No. Its purpose is to act as a collaboration tool, a VPN alternative, a network mobility tool, a testbed for the development of software that takes advantage of fully open networking, a virtual LAN party for gamers, and so on, but it's not intended (or able) to replace the core of the Internet.
+
+**Q:** Can I bridge this to a physical port and plug in an Xbox, PlayStation, etc.?  
+**A:** Not currently, as foreign Ethernet frames are not forwarded. This may be possible in a future version.
