it seems a lot of folk think prepending acrually works.

I mean, there's prepending and then there's prepending 50+ times...  Has
the latter EVER been useful in any way, shape, or form?

for ~4 yrs or so there's been possible problems with as-paths longer
than ~50 (I think, i can't recall the exact vendor bug)
so, folk should have already been denying announcements with longer
than ~soemthing-like-45 asn in the path.. right? :)

(yes, any prepend past ~10 is arguably not worth the time)
