I have no direct knowledge of the situation, but my guess: I suspect the proposal was along the lines of longest-path / best-exit routing by Level(3). In other words, if L(3) carries the traffic (most of the way) to the customer, then Comcast has no complaint--the costs can be more fairly distributed. The "modest investment" is probably in tools to evaluate traffic and routing metrics, to make this work. This isn't really *new* to the peering community, but it isn't normal either. If anybody knows for sure, I'd be interested to hear. Cheers, -Benson
