This is happening in the DFZ today.  You don't have to take my word
for it.  Log onto a router and check.  You can even find 65535 in DFZ
AS_PATHs even though that is not a valid ASN!

I think it's called a Private ASN and by its very nature, it ought not
appear in a DFZ AS_PATH.

However, since some networks are actually doing this right now,
perhaps it is worth asking them why.
