Now that's two people begging you to add stratum support

Agreed!
Alternatively, do you know what backend upcpu uses? Looks a lot like the 1gh pools and supports xpt.
No, I was actually quite surprised they had xpt.

Like you, I'm using mpos. Looks like there are some challenges to make RIC fit their performance metrics and stats. Do you really just have zero/one miner online and no blocks or is that an mpos issue?
