The problem with the brake comes from the "V" formed by the two crown arms: the "V" doesn't leave enought room inside itself to contain a caliper brake.

Yes, please, and thank you.
Several folks missed my comment in my second post about a behind-the-fork-brake.

Regarding rear brakes, I can stop faster with back-pedaling than I can with a rear brake, and I have no special skills nor strength.
That said, for my tastes, a rear brake undoes the aesthetics of a fixed gear bike.
