Feature request: e-mail notification when miner efficiency drops below a certain value.  The reason for this is because I've twice had what is either phoenix or my card crap out on me, where the miner would continue to receive shares from BitcoinPool, but not solve them.  When this happens, my efficiency dropped pretty quickly, and I had to reboot my machine to get things back on track.  The faster I could get notified to do this, the better it would be for myself, as well as the pool.
