Hi Randy,

Yes.  We can never have the knowledge of *all* BGP speakers
in the world, then keeping a 4-byte ASN announced to let 
everyone observe it looks a good strategy to see what would
be happening. 

The test you did has already proven that the current Internet 
routing system has no serious problem with 4-byte ASN.
( Did it have any? )
