We just had a similar battle regarding LSM extended attributes on files,
the biggest problem being what a module should do if it doesn't understand
the formats and semantics of the previous module...

It's certainly *doable* - the telcos have been doing this since whichever

big question is whether it will still look like Linux if you implement it.
