I've no idea how the setup would go, but there's also a "Memstore" backend. It's used exclusively for testing, may or may not scale well, and doesn't have integration with the tooling, but it's got very limited setup (I think you just start an OSD with the appropriate config options set). You might want to look at that. -Greg
