right.

right.

sure... which was what I was addressing. If comcast runs these boxes,
how does flix aim their customer 'through' them? how does flix assure
their SLA with their customer is being met? how do they then avoid
(and assure the traffic is properly handled) these boxes when problems
arise?

I get that the network operator (comcast here) has the best idea of
their internal painpoints and costs, I just don't see that them
running a set of boxes is going to actually happen/help. Also, do they
charge the content owners (or their customers?) for data that passes
through these boxes? how do they do cost-recovery operations for this
new infra that they must maintain?

right, that was the point(s) I was trying to make... sadly I didn't
make them I guess.
