I've never understood how the internet works, but all the StarWraith games past SW3 have had a multiplayer internet connection. Evochron Legends comes with the multisync dll, and I assume it can handle a WAN connection (I've never played online myself, but it's one of the big selling points)
If you download the trial of DBPRo, and look in "Dark Basic Professional\Help\documents" you'll find a file called "2 Multiplayer Secrets.htm". It's a multiplayer tutorial written by the guy who created StarWraith, and it
is very good. I'd upload it here, but I'm not sure if I'd end up in trouble with TGC.
Failing that, you could always ask on the StarWraith forums as the game's creator ('Vice') is very helpful, and even has a board devoted to game making!
