hmmm, I hope this wont happen to soon since right now I have over 200 BTC still unpaid and without a decent chance of recouping atleast some of it would simply suck. Unless you figure out a way to start rewarding only those who still mine at the pool from new blocks generated since it seems a huge volume of users simply stopped and is now piggybacking on remaining miners who still clear blocks for the pool, these loyal miners would be affected the most since they constantly will have unpaid balances.
