Sorry, I've lost the link, but ran across an item yesterday where Microsoft intends to integrate hardware based security with their next operating system. Specifically to prevent access to user files through the use of a boot disk. Sounds like ATA-3 type security that we've discussed here at length.
Greg,
Any luck Googling for it? I plugged in Longhorn and 'hardware security' and got a lot of links…

Secure Startup
Planned support in Windows codenamed "Longhorn" for Secure Startup technology provides higher security through use of Trusted Platform Module (TPM). This support addresses the lost or stolen laptop scenarios with TPM-rooted boot integrity and encryption. Secure Startup technology provides secure boot, hard drive encryption, and TPM services. In addition to addressing the lost laptop scenario, this feature also helps protect data in the enterprise space.

There is an Executive Overview doc here:
Annoyingly, not the first time Microsoft have used that TLA.
