I wonder what's so proprietary about their algorithm. I'd assume it's just Reed–Solomon coding on a UDP tunnel (or, alternatively, modifying TCP to accept partially mangled-packets if FEC is successful).

This could be demo'd very easily by gluing together: udpcast (http://www.udpcast.linux.lu/satellite.html http://www.udpcast.linux.lu/satellite.html) -> Sends/receives files over UDP. Supports FEC. netcat -> Join file I/O (from udpcast) to local TCP/UDP sockets openvpn / iptables userspace -> Provide connection routing. Seems like an evenings work. Edit: udpcast might not be suitable for this. I am surprised noone has already built a simple UDP FEC tunnel program...
