aha, I was thinking about the same idea as Sam Tetherow has stated, but didnt know how to make it work.

But ya, basiclly i would like to have a record of usage for each IP address (currently 16 soon 32)
yes route goes thru the "lil linux router that could"
and into Proliant hell. :)

Thankyou guys for the input.
