This thread might be a bit inactive, but I have to admit that I found it quite useful today as me and my brother wanted to play a round of Rebellion but there now happens to be a few routers and a few hundred miles between us. Hamachi I was familiar with, but we couldn't get the TCP/IP to work (no games showed up in the list), but I wasn't about to use some 30 day trial software that only works for an hour at a time (we played a 9 hour game today) and I wasn't about to pay $250 for it. So, I decided that there must be a free solution for emulating a serial connection over TCP/IP and, lo and behold, there is. It seems to work a lot like the program that's mentioned earlier in the thread, but it's free instead. I just figured that this might help some people out: I got it here - http://www.hw-group.com/products/hw_vsp/index_en.html. Enjoy. (We experienced a lot of lag when there were over 100 capitol ships in battle all at once, but I'm not sure if that was a fault of the connection or simply that the game isn't designed to cope with things like that.)
