Rod,

I have very little experience with extremely high loads like you're 
discussing. However, I do know that you could build a MySQL cluster and use a 
cacheless usrloc setup on each of your OpenSER servers. This would let you 
scale very easily; just add more servers.

Additionally, since this is cacheless, I don't think the servers will have to 
keep all of the users in memory, either. Could someone more knowledgeable 
please verify this?
