One thing that seems not mentioned in bit-thereum is the "as long as everyb= ody agrees" escape hatch, i.e. one branch which allows spending to anything= (including a transaction that violates the letter of the contract) as long= as all participants agree. This is gives my newer mechanism the ability to "fix" buggy contracts if ev= erybody involved can agree to the terms of a new contract, by simply abando= ning the existing contract and spending to the new contract.

Often this means creating a new blockchain, or= at least a sidechain to an existing blockchain.
