On a somewhat connected note I ran into some Mobitv guys the other
week and they indicated that all the last mile for them was best
served on current tech using unicasting. Multicasting is used for
delivery to the last edge server in some/very few cases.

It seemed to me that unicasting is also the preferred model since
providers can bill viewers quite easily for bandwidth consumption, and
can easily nail 'abusers' (>5Gb/mo data usage) with a per Kb charge
for overages. In essence unicasting although less optimized from a
bandwidth point of view, is better from a profit point of view.

I should also note that (putting on my CDN hat) unicasting is more
profitable for us as well. We really don't care very much about the
bandwidth (when you have a dozen+ OC192s it becomes irrelevant), and
large scale broadcasts can be distributed via HTTP caching to edge/pop
server clusters to scale the load.
