- signal your ip address (which will tell me v4 or v6) and, as
  it is the 21st century, assump MPBGP
- signal your asn.  if it is the same as mine, it's iBGP so
  no need to think about multi-hop etc
- signal how many hops i need to get to your listener
- signal the authentication

isn't the rest either discoverd/agreed in the OPEN or automagic?
