True. It's just that live seldom really have to be live (and very seldom is) and
that there are free caching services out there that could be taken advantage
over.

Non-choppy video is molto expensivo....

Depends. If you want it to appear live, the human minds (even techies) can
easily be led to  believe that five minutes is a believable 'latency'
for encoding
and routing little itsy-bitsy tcp-packages through a series of pipes
before it ends
up on your screen.  Just don't show a live clock in-picture...  (or
set in five ahead).

Technically feasible?  I don't know...

Indeed. Except I don't see much mention of the bandwidth issue which should be
no. 1 if anyone considers any streaming...
