there was a british single-speed freewheel that would do this - basically, it was a freewheel that had these pins that you could engage remotely (via cable) which would lock the 2 pieces together to make it a fixed "cog".

ive ridden a bike with one, and it seemed to work reasonably well, but frankly, felt a little sketchy. engaging the locking pins felt a little dodgy. i certainly wouldnt trust it for any heavy usage. the trick is how to smoothly engage the locking mechanism.

for the life of me, though, i cant remember the manufacturers name...
