The problem is that even a tiniest service provider doing BGP with some bigger provider can kill most of the Internet by injecting a single bogus route. (I expect to hear more "RS will fix everything" speech at this point. Relax. It is not here yet; and we had occasions when bogus routes were killing ANS connectivity per-network filtering notwithstanding. There are bugs and interesting incompatibilities :).
How about a speech that sez "Sprint will fix everything"? There was a comment made in Boulder that with the addition of Curtis's ideas on route damping and some judicious other tweeks, that an RS could do just that. We agreed to work on adding just such features to the RS code. It is not clear that there was a client demand for this feature right now. Now if Sprint were to become a RS client, and asked for this feature, I expect that it would get higher priority than it does now. --bill
