"potential new and different architectural approach" to solve the Comcast - L3 dispute

[Loránd Jakab <ljakab () ac upc edu>]

Since it is Friday, maybe some of peering experts have some time to
speculate what this new approach proposed by Comcast might be, as they
assert it would represent "a significant shift of Internet infrastructure."

Well, their previous proposal was already representing quite a
significant shift, and not in a good way, but I wonder what the new
offer could be so that they figured it would be more acceptable to Level 3.

I hope due to the speculative nature of the question it will not be
considered off-topic.
