Hmm, definitely interesting. I think people archiving a whole lot of=20
episodes of one series is quite common. We'd have to think about=20
whether the user will do the cut manually, or how we could detect=20
the similar sections (shouldn't be that hard really). And ofcourse=20
the format should support it. Then there's things like deciding in=20
the player what to do when the referenced file isn't available. And=20
what about when you want to stream such a file, would the server=20
piece it together first, or is should the two files be streamed=20
separately.

Thinking of applications, this could also be interesting in the=20
context of online radio and television, where you could have=20
commercials in separate files. Ofcourse, they'd have to be streamed=20
as separate files then, and cached on the player side.

Good idea, lots of things to work out but nice nonetheless. I need=20
to get back to video coding one of these days...
