I've been mining here for more or less a week now and I'd like to give a little feedback.
First of all, the minor issues due to the DB upgrade aside, the pool works great! I was switching pools with a Perl script before mining here. While that works as well, keeping track of several pools and there respective fees is quite a hassle. So thank you for saving me that daily headache.
Regarding the possible changes that have been discussed in the last pages:
Auto-conversionIf you're going to implement some auto-conversion to another currency, consider BTC instead of LTC. Unless you can exchange the altcoins directly for LTC, I'd pay exchange fees thrice where I only should pay them once (altcoin -> BTC -> LTC -> BTC).
Users that prefer LTC over BTC would just have to convert the BTC to LTC. Whether that's done by the pool or not, they'll pay exchange fees exactly twice.
Reward systemPersonally, I'm not a big fan of PPS. PPS comes in two flavors: high fees (lower rewards in the long run) or low fees (big risk for the pool).
Rather than PPS or the current PPLNS + expiring shares, I think the nature of the pool (constant miners + multiport users) would benefit most from CPPSRB.
Since CPPSRB always pays the most recent shares first, that would eliminate the problem of constant miners' shares having to split their rewards with aged shares from multiport users. It might also mitigate the whining every time the pool switches to a high-difficulty coin and then back without finding a block. If the funds become available, those shares will get paid.
