I don't quite understand the security of this setup: The http-Requests 
go through the load balancer, ok. But Robert's ssh account goes where? 
To the load balancer, and from there to the webservers?

I don't really see how jailing Robert in a vserver inside a real server 
adds *security* to the setup, at least compared to a dedicated server. I 
see it's more convenient because you can setup a new server remotely, 
but other than that, does it make up for the performance issues?

BTW: I was wondering how hosting of the smaller sites (gov,edu,assoc, 
etc.) works or is planned to work. Does it make sense to put them on 
separate (v)servers? That would make administration of those much 
harder...After all, how many machines (real or not) are we currently 
using and how many after splitting hosting?
