Have you looked at using rrdcached ?
I'm not sure, but I think it may allow you to avoid installing all 
the graphing stuff on everything.

In addition, you can use it across a network, so you can collect 
stats on one machine, and store the database on a different one 
(perhaps centralising them all to one machine). That should also help 
with security since the machine doing the graphing won't need access 
to the machines generating the data - the databases would be local to
