yup.  and if they want to be seen on broadband tv, they have to get
broadband tv broadcast service.

a content site is not a 'consumer'.  they are provdng a servce.  if
they want to provide the service, they need things like mains
power, the appropriate ip service(s), etc.

no, the assumption is that, if you are providing a service you have
the service to provide.

exactly.  hence the subject line.  let's not pay the 90% to solve
the last 10% if we really don't need to go there.  we are providing
engineering not marketing and engineering magic.
