Hi Mike,

You make a good point, I apologize for not documenting some of the
ideas sooner. The architecture I had in mind borrows from other
queue systems I've worker on, along with feedback I've gotten from
various conversations while getting things started. For the hashing,
we could possibly reuse the distribution ring algorithm swift uses for
selecting server sets from accounts. I've added some sample deployment
descriptions to the wiki page:
