Luke: I'm interested as to why you chose to do the 'half implementation' now? I'm only running a small-ish miner at the moment, and it looks like I've lost maybe 0.75BTC total compared to what I would've expected on the last few blocks - nothing that's going to break the bank, obviously, but a few beers' worth that I would've liked to see! I can quite see that someone with more power pointed at your pool would be less than pleased about having to wait for the retroactive credit at an uncertain time in the future.

I don't want to sound too critical - I'm well aware you're putting in a lot of effort that benefits us all - but I do think an all or nothing implementation would've been fairer.
