This is a pretty generic question.

Generically speaking users aren't what most people think of but some 
good guidelines are:
    --   2000 simultaneous calls (probably more depending on your CPS) 
if you are not running any media through the box
    --   I'm not sure with media what the upper end would be ... but I 
would seriously doubt you'll get acceptable performance of more than 500 
- 700 calls on a single interface

OpenSIPs works well as a load balancer.  As for FS itself there is no 
built in mechanism to share state across multiple FS instances ... 
however you can do it yourself with mod_event_socket.
