BiggusGeekus: I would
soo love to play in that campaign

It would be so much fun applying the pc's futuristic mindset and knowledge to a typical D&D world. Besides, it would take care of a the problem of 'teaching' the players enough of the world background to realistically play a native character, since, in this case, they shouldn't know anything about the world. Lovely
To answer the original question:
Well, any campaign really... sadly I have several settings, quite a few adventures and lots of time, but NO PLAYERS! :\
One thing I would like to do, is play a campaign in my homebrew, with the pc's as members of The Calmoran Adventurers Guild. Ideally it would be three different groups each playing an important, but different role, in banishing the eternal darkness from the world. Occasionally there could be crossovers between the groups, or maybe cooperation between them. The groups should be small, 3 or 4 pc's in each, which IMO gives good gameflow, while allowing two or even all three to get together for an adventure, without making it completely unmanageable.
That, or just a standard Eberron campaign
