Ok,
The servers in the DMZ provide Mail, web, wiki, ftp, minor DBMS and version
control.
The FTP and version control can demand high bandwidth - but these are
exactly the places I would like to have an extra check for, so we don't get
a virus checked in or infecting the servers from an infected laptop.
The external connection is 2 up/ 4 down business cable (he said with
trepidation)

So, (he said cringing) how far up the scale do you have to go to get AV
running at better than, say, 50Mbps?
