I think I see where the miscommunication lies. We were  
discussing ISP's running IBGP sessions with multi-homed  
customers. giving you the ability to announce routes to  
another provider tagged with my AS is what makes me  
nervous.

        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.
