I misunderstood Bob's original proposal. I thought he was suggesting
"hardwiring" the message response/ack mechanism to use a set fixed SSn-N.
That being said, how often does SSn-N actually get used?
Is it really useful for anything?
It would seem to me that probably the greater metro area on both sides of a
border have more in common with each other, than either side does with the
rural interior of their respective states/provinces.
