You seem to be mistaken that any bandwidth issue will be remedied by 
TLMC. A significant number (well over the 50% mark I'd wager) will not 
be remedied. This thread was started over such a subject.

The Apple TV cited as an example was an example. Travellers, be they 
corporate or leisure, have significant networking needs that the TLMC 
cannot address. Just think of "The Cloud" (yes, I'll go and flog 
myself for bringing it into a discussion on NANOG), where people are 
storing their (semi-) private documents or files - in the end it's 
similar to connecting back to the office to access the fileserver.

And pray tell me, why should they all have TLMC's ? If the concepts 
and technologies underlying "The Internet" were invented to have the 
same ubiquitous speed for all, I think it would have a fairly 
different design. Now if you're a content provider, then yes I can 
imagine why you'd like everybody else to pay for better ways to 
deliver your content without having to pay for it yourself.

The examples you cite are the prime examples where users either bring 
their own entertainment, or it is already provided. On a long airplane 
flight it is quite uncommon to not have some offering with movies or 
audio, free or paid is outside scope since TLMC's won't be free 
either. After all, when I sleep or travel on the road my bandwidth use 
is vastly different from when at home, work or at a hotel.

Within this discussion we're talking about the actual last mile. A 
proxy or cache won't be of any use if the users can't get to it with 
sufficient bandwidth to make it work anyway.
