Routing ethernet traffic between peers inteligently. Thus allowing for multiple networks to share resources and even IP address space. Some may call it a VPN (Virtual Private Network) application, but it's much more powerful. Differences with traditional VPN technology:
Yeah - I don't quite agree with this in the traditional P2P sense, however I think they mean that they can connect multiple sites and have data transit between them. I'll cut them a break here because it's hard to describe how it works in so few words :)
2. It doesn't require licensing
Yeah - I wasn't too sure about this either. I haven't seen any VPN software that requires licensing in years. I didn't know anyone still required this?
3. It is much simpler
4. It operates at Layer-2 (Ethernet), VPNs generally operate at Layer-3 (IP)
I was thinking more the case of joining lans. Obviously its not a solution for all causes, as anything with more than 5-10 nodes per site and more than 2-3 sites would get pretty ugly. I think a nice thing would be for things that can ONLY use a local LAN due to either software or developer restrictions.
From my understanding, this software is pretty much acting like a bridge, but with endpoints over a routed IP network.
I've used a lot of VPN stuff in the past, but I've usually always ended up doing it on a router, then had to NAT over it and all sorts of nasty stuff. I think this is a nicer solution if it could be implemented right :)
A criticism of uvlan in particular is that I wouldn't trust my network security to people who sound so clueless. Their derision of VPNs, as you quoted above, shows either a lack of sense or a blind hatred, using libpcap in this situation gave me some chuckles, and their "What algorithms are used?" page scares me a little. I'll stick with OpenVPN, myself.
I think it's come about of a case of wanting to do stuff that won't work properly over a routed network (xbox games etc) - however could be nicer for a lot more things.

Damn typos. I've just changed numbers, I must have typo'ed it when updating the sig on my desktop. At least it's right in other places ;)
