 well, once upon a time....  you weren't really considered an "ISP"
 unless you were able to play the BGP game.  So an ASN once was an
 hallmark of an I{A,S}P.  Things change so I expect it is much harder
 to figure out, externally, what an I{A,S}P is than it used to be.
 I still use the ASN token as a discriminator. YMMV

Additionally, you need to subtract out the ones that have gone out of
business.  I was looking thru the ASN list and right off the top found
about 5 that I recognized as defunct within the first 5000.

(ok, ok, 5 / 5000... maybe you don't need to subtract them out after all)
