I have read it now. I will look over the code for H1 [1] and also try
to contact the developer to get some info about how well it scales.

The other idea that I had in regard to uid generation is very well
described by Ted in this mail [2]: create servers that do uid
generation and use Zk to coordinate them, somewhat similar to what
region servers do in HBase. Each server will be responsible for
creating uids for a shard of mailboxes.

Clients will interrogate ZK to get the list of servers and then
connect to the server they need for each mailbox.
