Well, our system is designed for 100.000+ users with the possibility to 
scale to an arbitrary number... and it works pretty well... an overview 
of the system is given in chapter 7 of http://linguin.org/thesis.php

It's quite simple. What you need is some basic knowledge in heartbeat or 
any other FMS and in MySQL-Cluster.

Basic tests with one balancer and two proxies revealed a rate of ~160 
call attempts per second (with a quite complex routing config with 
 >1.000 lines) and ~600 registrations per second, so this should be 
enough for most of the setups out there...
