I see how this works. It takes advantage of standard functionality in most routers to essentially do dynamic port forwarding. I didn't know much about UPnP, probably because I never play online games :-). It does not require an end connection, as I had thought before; it just fiddles with stuff on the router itself using standard protocols. It's essentially punching a hole in the firewall and forwarding to your machine. This seems perfectly fine, I think ('tho, I wish the UPnP thing that you found didn't require Java!).
