by the way, when I see AS 2 or 3 at the end of path I immediately assume
that someone has been confused by the syntax of their router and meant
to generate 

        64496 64496 64496

but instead generated

        64496 3

the opposite error tends to create very long (but non-hijacking) AS
paths which occasionally cause operational problems.
