We'd do it as long as everything looked legit (i.e. it really seems to be 
the customer's IP space).

We've done this as well.  Whats wrong with letting the customer use their 
ASN and BGP peering with them in your data center?  They might even get a 
connection to someone else there and multihome again.  Either way, the 
routes are getting into the global table...does the end of the aspath 
matter that much?
