Slightly different approach... Needing to multihome is justification
for requesting an ASN. Is this strictly necessary? No. You can source
the block on his behalf but that creates various routing
inconsistancies. There are other even more unpleasant ways of doing
this that are perfectly feasible. (I'd be willing to use them if I was
the client since I know what I'm doing but I would not be willing to
have a client of mine use them because it would scare the hell out of
