I've decided on the first version of my multi-player internet game that I'm going to host on my PC (now that I've got a static DNS). I decided on a MUD, since I'd already started writing one based on the GTA universe.
After a bit of polishing up, it now works, though is very limited in location and content. Anyway, if you've got nothing else to do, give it go! It's called GTA-MUD. The GTA stands for "Great Text Adventure", for legal reasons obviously. Let me know what you think!
