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.
