Masquerade: Any large network limits?

I have been asked how many users can be masqueraded
with ONE linux server. This would be with kernel 2.0.33
with ethernet only connections and connected via T1 to
the Internet.

At a local college i have a small intranet with about 60
machines <three student labs> running through a similar setup.
This has worked very well. Now there's a possibility of running
an entire county schoool district through a similar setup.

With a recent Pentium box and of course PCI controllers "all"
Is there a memory problem although will probably have 64 Megs
Net cards will be Tulip based and probably Buslogic scsi.

Major question is how many connections can linux masq "reliably"
ie: 1000 connects? what about 5000?
Would like to hear from anyone masquerading a large network and
there real life results.

We are considering using one machine for the entire district or
if this is bad then multiple machines with a school or two assigned to
each box. Hence the question of: what are reasonable expectations of
one box handling?

TIA
