I am somewhat concerned about spyware filtering at the network layer
(and IPS systems in general). The catch is that false positives show up
as random network lossage. As in someone attempting to transfer a file
of research data that never seems to get through, etc.

As for the Barracuda, you need to be careful with it if you tend to send
large mailings to your users (legitimate mailings that is :-) ). The
Barracuda, normally configured, will let the first 50 through and then
stop taking the rest. You will need to carefully configure white lists, etc.
