P2P VPN implementation currently without any encryption. Supports Windows and Unix variants. Features include:

Simple NAT Traversal using UDP (similar to STUN, not the same).

Automatic address assignment to new peers

Emulates a LAN between machines

Note: Scurry currently has no encryption layer or authentication mechanism at all. Also, the packet switching is currently implemented using Data.List.lookup as opposed to something more appropriate. This really isn't much of a problem until you hit hundreds or thousands of peers.

Requires a TAP-Win32 driver to run in Windows. Requires the tun module to be loaded to run in Linux (expects /dev/net/tun).
