Holdon, i don't even see the need for that; if you traceroute out, the
packets will cross the exchange irregardless of whether you're announcing
it to your customers, and a message of TTL exceeded will be generated
from the exchange's address.. The important question is, should they
be globally UNIQUE for troubleshooting purposes? I think so.
