Won't work because no one will sign that contract.

Hi Doug,

Verizon Business is willing to do settlement-free peering with you but
you won't agree to a reciprocal penalty if either allows its customers
to forge packets? I call that a weed-out factor. Weed out the bad
actors because anyone else would consider that peering arrangement too
valuable to pass up.
