Clearcoin requires 6 confirmations...
Actually, Clearcoin only requires 3 confirmations.And now that I've got some pressing core bitcoin stuff off my plate, I'll get back to working on a -testnet version of Clearcoin, and as soon as that is done I'll be announcing a JSON-RPC API so you can write code that interacts with clearcoin (creating escrows, getting their status, releasing coins if you're properly authorized, etc).
