(2) Could anyone share opinions/facts regarding why organizations may or may not exchange routes via the Route Servers rather than direct peering relationships at the NAPs?

I know of no case where an organization "may not" exchange routes with the Route Servers.

I do, AS1800..

Hum... Lets looks at this for a bit. 27% whois 1800 SPRINT (ASN-ICMNET-2) Autonomous System Name: ICM-Atlantic Autonomous System Number: 1800 ICM is the NSF project for International Connection Mangment yes? Are you intimating that the NSF ICM contract prohibits it from working with the NSF RA project? Perhaps someone from the NSF would be willing to give us a reading here. I had thought that these two NSF projects were to work together to improve the stability of the global Internet routing system. I'd would appreciate some clarification here. -- --bill
