Agreed, I was also doodling out some protocol format and kernel API ideas for
this.  We have a short week due to Thanksgiving here next week, but why don't I
email you after the holiday and we can exchange thoughts? I think a netlink
stats protocol would be a great way to solve the process-private/global access
problem.

Agreed, it will do, and if we do a good job with the kernel API for the netlink
idea above, maybe we can even inherit existing stats transparently.
