You're right that on-demand scanning has a high CPU cost. But Intel haven't bought McAfee to change the on-demand settings.
They're going to move security into hardware. Moving it out of the OS and further down the stack is smart, especially regarding rootkits, and will make attack vectors harder and more firmware-specific. Intel has already been adding support for virtualisation and cryptography (see i7 series).
All of this combined is very interesting to anyone running a lot of iron and/or VMs on top. You get a performance increase, plus remove the hassle from keeping AV up to date at OS level. Consumers will probably benefit eventually too.
This acquisition is also quite interesting in light of Intel's move into mobile. Sandboxing isn't going to keep mobile OSes safe for long.
But coming back to your original point about massive govt/military AV subscriptions, I'm presuming that Intel has a clue, and isn't doing this just to bump short-term company figures.
