... and that both conditions will continue for the duration of the 
video's playback.

Right?

Determining whether this condition holds either making some assumptions 
that may or may not be true or having some magical future-predicting 
technology.

If nothing else, I'm thinking things like "I would like to buffer up 
this 3-hour-long-video so I can watch it on the plane, where my network 
bandwidth will be precisely 0".  Definitely as use case I've had.
