Did I miss something? BitWall sits on top of Coinbase. Coinbase right now eats transaction fees (or if it is Coinbase 2 Coinbase, then it's just an "in the network" transaction that possibly does not need to hit the bitcoin network and incur a transaction fee). Satoshi Dice is an example of how not to do volume micropayments because you incurr transaction fees. If you want to do micropayments the right way, either you need to sit on top of someone else's payment network, or build your own. The biggest fees right now are the hassles of opening and waiting for an exchange account, and the associated exchange fees associated with converting $ to bitcoin, and bitcoin to $. With something like BitWall, you can start accepting and spending bitcoin without the hassles of dealing with an exchange.
