not sure why a config will help you any more than RR info which is much easier to get and maintain.. ultimately if you want more detailed data you need a complete view from each border router your interested in.. On Mon, 2 Dec 2002, Mark Radabaugh wrote:
if you run a network that has choices to make (more than one BGP speaking neighbor), you can help us by donating your bgp config files. abstracted or anonymized versions are ok.

I'm not sure if you want the bgp tables or the configuration itself. In any case http://www.renesys.com/ currently has a project to collect bgp views - you may wish to talk to them. There are also many public route-servers that can give you a good view of the routing tables.
http://www.caida.org has done a lot of work on analysis of BGP
