It could pop open a window when a users starts a browser and ask for a
username and pasword. Also, it could automatically get that information
from Windows (if they logged onto a domain).

Squid would take care of Internet usage *not* email - unless it was
web-based email like gmail.

Again, Squid can check those same credentials to allow or disallow.
JoeUser gets the same Internet access wherever he logs on.

If Squid does authentication by the IP then you see usage reports based
on IP. If you authentication by usernames then you see usage by
usernames (much more helpful).

Mostly web based reports. Nothing to pretty.
