So, Artemis, the spaceship bridge simulator.
It keeps coming up now and then. "Can it be played over the internet?" I always ask. Someone, recently, said "Yeah, sure.", in the STO thread.
Who wants to try this? Grab the demo, get a bit of VOIP going, get a server, pretend to be starship bridge crew.
(Bear in mind that quite a lot of the time will probably be spent trying to get the network stuff to line up properly.)
