I have a good feeling that there will be a stable python port of the stratum servers available eventually which I'll put putting in BTC to help push the dev along to get it done. It's a tricky project so I hope it makes it to finish.
I myself ponder why altcoin devs on the SHA port don't add a way to have merge mine support with BTC. That way we can mine BTC, and send all lesser hashes to altcoins. Would be a win-win for long-term miner support and for the miners as well.
We can only hope for someone to unify the coding so it happens and its easy to add to different coins.
