As yet unspecified hardware, which is why I am asking the list. :)

I seem to remember some very old idea that more than 4 network
interfaces on a PCI bus was a Bad Idea(tm). 

I know conventional wisdom suggests specifying an application and
expected load, but in this particular case I don't really know
exact numbers in advance, I can only determine that the load is
on the scale of ~100 machines, and several gigE networks.

I'm not bridging, I'm actually routing...so that will take some of the
load off the idea. The downside is I'm routing gigE and I don't want too
much speed to be sacrificed.

Perhaps. I don't have any data to confirm or deny this, though it seems
reasonable.

Do you want to examine a socially conditioned individual who
attributes what has been done to him as the work of a higher power?

All you need to do is look at 9 out of 10 "dedicated" people.
