Now you're talking :) This is exactly the kind of "generic mechanism" that 
benefits far more than just selinux that I've been wanting. I've zero 
objections to the concept as a whole, quite on the contrary: this is one 
of the most wished for rpm features in recent times.

What I think does need further thought/discussion is how the collection 
data is stored and some other ideas/ponderings .. more detailed commentary 
on the individual patches to follow. Details aside, big kudos for this. 
It's something I definately want to get merged, the sooner the better.
