though sometimes you need to do things with packets that
require interaction with a database of reading from files etc..
I put it to you that having a general way of getting the packets 
out of the kernel is  better than adding bloat IN the kernel to
do these things.

Certainly I had misgivings about adding stuff to the
IP processing path
so I am certainly happy to see if we can clean it up..

I like the idea personally of a pointer that is jumped to, that 
normally results in normal processing, but which can be replaced and
'chained' as soeren suggests.
