I think we should extend existing standards whenever possible. So: could we encode signature blocks or BIP-10 transactions using S/MIME ? Or is there a more appropriate "sign a message" standard we could/should use? You're glossing over little details like what character encoding is used for the message, but I'd rather leverage all the work already done by the IETF to nail down all those little details rather then re-discover them and come up with our own solutions. -- -- Gavin Andresen
