I have only seen defensive implementations such as the work of
Garfinkel and Rosenblum at Stanford.  Their use case is a modified
hypervisor that can monitor critical OS data structures.  One of their
implementations watches the Linux system call table and can prevent
modification to thwart rootkits.

I think it's a great idea, I'd be interested in seeing any published
work you have on the topic.
