I was going to take a look at this a bit myself, just try it out. I can't completely speak for the Fog/Edge/Massively Distributed working group in OpenStack, but I feel like this might be something they look into. For standard multi-site I don't know how much it would help, say if you only had a couple or three clouds, but more than that maybe this starts to make sense. Also running Galera has gotten easier but still not that easy. I had thought that the OpenStack community was deprecating Postgres support though, so that could make things a bit harder here (I might be wrong about this).
