What will the load requirements be? (How many users will require the use
of squid).

I have a FBSD PIII 800 w/256M RAM as a firewall for one of our clients,
with 3 OpenVPN instances running simultaneously (Two are site->site, and
one is an XP-client->site). The box is also performing NAT (ipfw/natd) for
the internal users, which when all are accounted for equal ~120, and I
find it works great. There are about 30 users through the VPN's, though
usually never on all at the same time.

Depending on caching requirements though, you might be better off
splitting that off onto it's own box, especially if you have the hardware
readily available as you suggest.

YMMV.
