I've been doing some things that collect volume statistics nightly  
(vnode usage, size, etc) and stores them in a SQL table, and I  
periodically run a perl script that does volume moves of user home  
volumes based on size & usage in an attempt to balance out capacity  
and IO load amongst a collection of servers.

I'll see about posting the perl script that does this (it's not  
actually that pretty) to the list next week if anyone is interested.
