----------------------------------------------------------------------
Unfortunately, I don't have a lot of detail on how customers want to use them.
Current requests come from Target, Openwave, and one other company. My notes
just say they've tried counters and instead want Oracle-like sequences. If more
detail is needed, we can try and go back to them to see if more info can be
had. Lastly, this isn't a constantly recurring request so not exactly a white
hot priority.

> UUIDs are usually the right choice for surrogate keys, but sometimes
> application constraints dictate an increasing numeric value.
> We could do this by using LWT to reserve "blocks" of the sequence for each
> member of the cluster, which would eliminate paxos contention at the cost of
> not being strictly increasing.
