Have you considered taking a fee for the pool? Maybe something like f=c=0.005 (1% average). I don't know if many people would mind, and it might make it worth your while even without participating yourself.
I would stay and pay the 1%.
Actually I don't really know where to go. PPS-pools are out of the question, the original Multipool is not operated anymore (and I didn't see my coins from there yet), Multiclone is also not stable, deepbit-PPS is too expensive.
Meni, would you care to comment on Eligius' new MaxPPS-system?
