I'm looking at doing the same at the moment.

load-balance should be OK with e.g. plain PAP etc.

As soon as you move to EAP then it'll break, so keyed-balance
should be the only real option AFAICT, though I have considered
ideas using unlang to choose the proxy server and storing it based
on Calling-Station-Id and User-Name in a local redis server with a
timeout. But I usually look for the complicated solutions...

My likely plan if I go ahead with this is to use keyed-balance
probably with Calling-Station-Id (and possibly also User-Name) as
the key source.
