F-Zero VS
I discovered a few days ago a blog explaining how to play a multiplayer mode in F-Zero running in a modified version of snes9x.
I hope that one day such feature will be possible on hardware with a action replay like device to patch the game and a way to communicate between two SNES.
Here is the F-Zero VS blog.

Details on how this could be done with real hardware.

You should take that up as a project, it would be awesome!
