On a related note : Do ISPs ever tweak around with Local Prefs and weights so as to select BGP paths with greater AS PATH length?
Would it ever make sense for a provider to chose a longer AS PATH length BGP route against a shorter AS PATH length route?

Hi Chris,
Or, you just don't want to send traffic through Bill Manning's ASN because
you dislike his hawiian T-Shirt Policy? There are probably a few hundred
reasosn why you'd avoid an ASN... In general though I'd think that like
Michel said: "It's a pain and its doing something that bgp should do for
you without lots of messing about"
That's why i explicitly asked for some "social/political/etc."
reasons where an ISP may not want his traffic to traverse some
particular AS number(s). Something which is beyond BGP to determine
as of now ! :-)
