I'd think some kind of process ACL's would be a better approach - something
like 'yeah, you're root, but you don't have this-and-this capability/token/
whatever, so there!'.. I don't know how far the ACL work has progressed,
and if there are any ideas to go in that direction, but ACL control over
sending signals certainly sounds interesting.

G'luck,
Peter
