A couple random thoughts I've had about this miner:
1. Once we crack the sgminer and do more algorithims, I'm sure Baikal will release their version to the public.
2. I was thinking about how you could multimine with just one Baikal X10. If you get your hands on another Orange Pi Zero, with the extra pin headers, and an extra control board, than what is to say you couldn't take one or two hash boards out, and put them in another case?
3. Also another thought about multimining is, what if you could setup a cron job on the Orange Pi Zero to switch pools every few hours. I know there are auto-switching pools, but it would be nice to say, mine DGB / Qubit on one pool, then four hours later, switch to Verge / Myriad-Groestl on another pool. I think this could be done simply by making a cron job to update the miner.conf and miner.pools.json. I don't know. Then again, maybe it's just easier to use some autoswitching pool or software for this.
