It's not a bad idea to make statistics and payments with only the bitcoin address, but it's entirely anonymous, like Eligius. I don't know if people prefer a account with all their workers and the total balance and some statistics which come later when DrHaribo will find the time, or one statistic page per address. That seems to let public statistics for all people (like in future top 10 workers for example, that's seem we can see what people will earn, etc). We can't make an option to let statistics private, because how we know it's you? And DrHaribo considering to create a forum dedicated to the pool. I think it's a good idea to link website accounts to forum accounts.
Those who want a per worker stats, can just create one address per worker so that will obfuscate how much they actually earn as an individual.
