The only bounty we have left is one block (1772 SOL), but we might start mining up some to hand out as future rewards. We decided not to premine bounties in order to keep the difficulty low for the starting miners, and to avoid looking like we were grabbing handsful of our own currency. In hindsight it could have been a better choice if we had mined some to hand out, but the genesis block is almost 9000 blocks behind us now so no point in being wise after the fact
Ideally we'd like to see someone run a p2pool, and we still have plans to run a p2pool of our own, but spare time is minimal right now and with the currently low network hashrate our development time will be better put to use on something different. Perhaps the guys at p2pool.org would be interested in helping out.
