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 ! :-)

I believe with the responses that i received both on the list and offline, 
that it is indeed quite normal for ISPs to filter routes based on the AS 
Paths for 'other' reasons. Reasons, quite beyond BGP as a protocol to 
handle! And this can happen, when an ISP doesnt want its traffic to traverse 
some AS(es).

Thanks,
Tulip
