Hmm. I could /maybe/ see allowing that as a seperate
IBGP community, but even then it's dangerous.
It's easy to get an ASN (even though it takes a while;
I think the 'NIC still does those manually), so there's
really no reason not to require multi-homed customers
to do so if they want to talk BGP with you.
But, seperate real ASN or seperate community, you'll
still want to filter incoming announcements from the
customer -- just as they'd probably want to filter
announcements from you.
