Interconnect is not done at the core of the network.  GTT is.  No self
respecting SS7 network operator would connect your SUA junk to their
primary STPs any day soon.  Lot's o' luck.

SUA already has this concept.  Any element can be a relay within the IP or
SS7 domains.

Only M3UA needs the SG-SG concept because currently only an SG can relay, and
now only within the SS7 domain.

For M3UA, however, providing relay within the IP domain is pointless.  Each
originator knows the address of the final destination and might as well form
an association with and send it there directly.  M3UA relays accomplish nothing
more than an IP router already aptly acheives.
