Besides p2pool and eligius (and solo), which pools pay directly in mined coins?
Dunno.
But being paid at the threshold you set is one of the benefits of mining on a pool. I don't want to be paid in really small BTC fractions.
But Eligius does have a payment threshold. I only got coins generated to my address when I exceeded the threshold of 0.67 BTC. How does that work? It might be problematic with large thresholds, eg. in the extreme case that everyone has their threshold set to the block reward amount and start mining at the same time. At first, the pool wouldn't have any users who have exceeded their threshold, so they'd have to generate rewards to the pool's wallet. That can't be used for payments later, though. After users start hitting their thresholds, how can they be paid? Maybe such a system needs a small enough threshold to work in practice.
