yep. used them all the time for rear hub drives with front derailleurs - work great!
And since you have re-awoken this thread, I'll throw my 2 euro-cents into the pot: Schlumpf Mountain Drive or Speed Drive. Self-contained two speed inside the front crank case. Activate with heel of foot. Nice and clean, no need for chain tensioners. Keeps you as a 'fixed gear', although I agree this blurs the definition. But no-one will know but you!
