Perhaps I'm being completely dense, but why would the filtering tables have to be compiled into the kernel? Why not load them from user space via a mechanism requiring CAP_SYS_RAWIO?
How many commands are we talking about here? Is the mechanism workable by a simple bitmask, or is something more complex like a state machine required?
