I don't speak for Abilene or Internet2, but here's what I know. Abilene doesn't buy transit from anyone. Their internal routing policy is quite straightforward, given that it is goverened by the Abilene Conditions of Use (their AUP). The CoU would normally prohibit connections to commercial ISPs, but it is set aside for IPv6 (and IPv4 multicast). 

As a result, Abilene peers with a number of commercial IPv6 networks at locations where it is convenient to do so (PAIX, primarily). Abilene has excellent IPv6 connectivity to the R&E world, typically along the same paths and with similar performance to IPv4. They'll never have that good connectivity with the commercial world, and in any case once the commercial uptake of IPv6 is high enough, they'll disconnect those peerings and let their members get IPv6 connectivity through their individual commercial ISPs. I have no idea when that will happen nor how the decision will be made, but that's the stated plan.


PS - I have no interest whatsoever in debating R&E versus commercial, the role of Abilene, etc. I'm just passing along this info. . .
