Scalable, reliable key-value lookup service

Here's a great summary of most of the available key-value storage services from Richard Jones of last.FM - great stuff.

From what I can tell, Scalaris is only memory-resident at the moment and doesn’t persist data to disk. This makes it entirely impractical to actually run a service like Wikipedia on Scalaris for real - but it sounds like they tackled the hard problems first, and persisting to disk should be a walk in the park after you rolled your own version of Chord and made Paxos your bitch.

I'm leaning towards Voldemort, but need to look into this more.
