As I pointed out in my initial post on the issue, SatoshiDice is pretty much unaffected by the patch. They just have to deduct enough from incoming bets to make the "you lost" output economical and they're good to go. IIRC they already deduct fees on low-value bets anyway. On the other hand, the patch makes a clear statement that Bitcoin is not for microtransactions. If succesful it will gradually force a number of users, ad-based faucet sites and the like, to off-chain transactions or off Bitcoin entirely. The payment protocol has nothing to do with that. -- 'peter'[:-1]@petertodd.org
