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? Rohit MTech Comp Sc.

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).
