Thanks for writing this. It's great to see somebody run with the contracts
protocol.
Your proposed protocol is simpler than the one I suggested, so I updated the
Contracts wiki page to use it. However your implementation, as pointed out
by Gavin, is too complicated. See my proposal on the wiki here:
https://en.bitcoin.it/wiki/Contracts
I think you can just use an output script of
2 <K1> <K2> <K3> 3 CHECKMULTISIGVERIFY
