This is kind of a random thought, but it would be interesting if JJ2 had some form of VPN connection built in. It seems like it wouldn't take that much work to get the list server to host a network, and for the JJ2 client to invisibly join it, thus forever destroying the 30 second time-out problem. However, it might take significantly more work than I realize.

Either way, I think lots of people would like that.
