But the easiest thing I found in the end was DosBox, believe it or not.
Sure there's Dukester, and Skulltag, even KArena. VDM Sound, Dukester, JonoF's ports (which are quite well done btw), but nothing really supported mutiplayer very well. There are some great ports, but there's never been anything where you can run them in one place easily, with internet play that I've found without installing a bunch of programs or without a lot of hassle. Unfortunately there's not a terrible lot of support for them anymore. I've been playing the old build games since they came out.
