He's not going to insert IP or ethernet packets at all -- he's only doing client-to-client relaying, and so just using regular sockets will do. In short, the host running a VPN is not in this instance an endpoint for the VPN -- the only endpoints are the clients. (I had a discussion w/ him about this on IRC before he posted to the list).
