  If you filtered me by MAC address I could swap cards and get in.

  Unless you did inclusive filtering, and then if you wanted to peer
  with me, and I had to swap a card, you couldn't.

  The gigaswitches do port filtering, I believe that was agreed to 
  be the better choice.

  I certainly hope it's a choice, at least, right Steve.... :)
