please correct me if I'm wrong, but 'fast lane' really is (in this example):
  'cableco' port from 'moviecompany' has 'qos' marking configuration
to set all 'moviecompany' traffic (from this port!) to some priority
level.

  customer-port to 'cableco' has 'qos' handling/queuing that will
ensure '5mbps' of 'moviecompany' is always going to get down the link
to the customer, regardless of the other traffic the customer is
requesting.

right? (presume that in the rest of the 'cableco' network is
protecting 'moviecompany' traffic as well, of course)

So, when there are 1 'moviecompany' things to prioritize and deliver
that's cool... but what about when there are 10? 100? 1000? doesn't
the queuing get complicated? what if the 'cableco' customer with
10mbps link has 3 people in the location all streaming from 3
different 'moviecompany' organizations which have paid for 'fastlane'
services?

3 x 5 == 15 ... not 10. How will 'cableco' manage this when their
100gbps inter-metro links are seeing +100gbps if 'fastlane' traffic
and 'fastlane' traffic can't make it to the local metro from the
remote one?

This all seems much, much more complicated and expensive than just
building out networking, which they will have to do in the end anyway,
right? Only with 'fastlanes' there's extra capacity management and
configuration and testing and ... all on top of: "Gosh, does the new
umnptyfart card from routerco actually work in old routerco routers?"

This looks, to me, like nuttiness... like mutually assured destruction
that the cableco folk are driving both parties into intentionally.

BTW: I didn't use a particular 'cable company' name for 'cableco', nor
did I use a particular streaming media company for 'moviecompany'...
Also, 'cableco' is short-hand for
'lastmile-consumer-provider-network'. Less typing was better, for me,
I thought.
