That's a good question for Rob. I was curious about the staking part too. Usually external miners don't require a wallet for Proof of Work (or variants). Proof of Stake requires a wallet (either solo or pool). Unless Rob is going to develop the miner exclusively for pool and pooled ABN. So, I suppose you could run a solo pool with your own wallet. I've always wanted a specific receiving address for mined blocks (so I know which computer is the best producer), so this may be possible with a p2pool.
