A distributed lock manager for OpenStack?

Totally agree with the one solution; it was what I (and others) was thinking was going to be an outcome of that session (which I was the other driver of) but it didn't turn out this way in the end (even though I tried to say we should really be opinionated). As far as the other drivers, yes, the point is well taken, and jepsen is a good base case and it might be the way we should handle new drivers (if they have not been proven jepsen safe, then they aren't allowed); redis would then get kicked out due to this (although for small enough deployments perhaps having a single redis that uses persistent storage and can *manually* failover to a secondary master will be fine). Overall we (as a tooz group) are figuring out the way to go here and there seems to be a few ideas (like this) that are being bounced around.
