Ever hear of MessageLabs?
I have a couple of friends that work there. They do real-time, network-based email scanning.
Their software consists of 3 or 4 different commercial (definition-based) engines to catch all the known viruses plus their own proprietary scanning engine.
It's a 6GB heuristics database that processes several million emails a day. In 6 years, it's never passed a virus, even unknown ones. You should see some of the mail stats, they're almost laughable -- they catch new variants and new viruses 12-14 hours before Trend and Symantec even RELEASE def updates...
Of course, this doesn't mean you still don't have to use desktop AV. 97% of all viruses come through email, so there's about 3% that there service can't catch.
