DVDs (PUOs)...BluRays (Java)...Web...

All evidence that the more technical power you give content creators, 
the bigger the design abominations they'll subject the world to ;) [1]

I actually once came across a professionally-produced, major-studio 
BluRay where pressing Pause didn't pause the video, but actually made it 
deliberately switch over to and play a *different* video instead.

This is why a good system is one that automatically does the right thing 
by default, and makes you work to do the wrong thing...if it's even 
important enough to have the escape hatch.

[1] That, of course, is not an "us-vs-them" statement: Programmers are 
by definition content creators, too!
