I believe I've heard about a couple instances where PA was used for 
health checks, load distribution, etc for "web-scale" applications on 
thousands of servers running Linux. ISTR in one case it was only enabled 
when needed for tracking down an issue? But this is hearsay, I'm not 
involved in any of the above projects/apps.

But no, not for chargeback so far as I know. I only saw that sort of use 
in academia similar to what others have mentioned - departmental 
budgeting, grant accounting, etc.
