  No reason we can't have both; then everybody's happy :-)
  
  I like Soren's "pointer chaining" idea .. as long as divert sockets
  are retained. Then you can use the kernel to do something if it
  is suitable (and/or you need performance), or if not, then you can
  always do it in user mode.
  
  User mode is also good for testing & debugging new things.
