I guess 'all the cost' means most of the cost, and 'no offsetting traffic'
means 'not much offsetting traffic'.

(yes)


However, is the real problem here the traffic assymetry, or the fact that
all of the traffic is coming from one geographic location?

Traffic Assymetry of traffic which requires (for lack of better term)
"transport" to the destination.  In the case of longest-exit routing,
the traffic received doesn't require much transit, nor in the case of
distributed content.

If it is the former, then there isn't much of a solution except to merge
with a network that sucks a huge amount of traffic. 

Presuming shortest-exit, correct.

However, if it is the latter, then wouldn't content distribution fix it?  
I know many web farms
offer distributed servers to their customers as a type of premium service. 
However, since in this case it benefits all parties involved, it seems to me
that it might make sense to offer this service to huge web sites at little
or no additional cost.

It's difficult to "know" whether the distribution is actually
working and resulting in interconnecti traffic which is local,
but otherwise, yes.
