On a related note, the hedges I had set up at Bitcoinica worked great......until Bitcoinica went tits up. Now, I am not only denied the hedge as BTC continues the move upward, I am also waiting on a refund of 100's of BTC I had on deposit. Any ideas on where to go in order to structure another hedge would be appreciated!
Sorry to hear that, and I hope you get your money back soon. Honestly, I'd just look for some kind of OTC contract with savvy people around here or on IRC. You get much more precise control over your terms. If it's big enough, you might want to mail a physical contract, but otherwise a GPG-signed contract would be sufficient to destroy someone's WOT reputation if they screw you (of course, you'd only want counterparties with high reputations to begin with, so they have something to lose there).
I've been doing GPG contracts for a while with people on #bitcoin-otc and have some fairly large and valuable contracts arranged that way.
Edit: by GPG contract, I mean a text file explaining all the terms and the parties involved that is signed using GPG by all parties.
