And that's the snap answer, yes.  But the *load*, while admittedly 
lessened over unicast, falls *mostly* to the carriers, who cannot anymore
bill for it, either to end users, providers, *or* as transit.

Will they not complain about having their equipment utilization go up
with no recompense -- for something that is only of benefit to commercial
customers of some other entity?

You're effectively pushing the CDN into the backbone, here; no?
