Actually, Cisco's scheme is a way to provide lock-in for Cisco and the big anti-virus companies. It lets Cisco sell new hardware, and lets the cabal decide which AV products get to be deployed on a corporate network. Not to mention, you suddenly need (useless) AV software for all your Linux, *BSD, MacOS, HP/UX, SunOS, etc. machines. This is a scam that provides just enough goodness that they may get away with it.
