This is a lot like a QuickTime movie.  The QuickTime movie format is 
basically a container format for time-based media.  Apple not only 
ships a bunch of video and audio CODECs, but also supports sprites, 
subtitles, "wired sprites" (sprites with scripting and decision logic 
and user interaction), arbitrary effects and transitions, and a ton 
more stuff...

Personally, I like the possibility of effects and transitions.  You 
can do things like have multiple overlapping video tracks in a single 
QuickTime movie and transition between them programmatically rather 
than rendering your fades, wipes, mattes, blue screens, etc. into one 
video stream.  (Or you can just work with multiple tracks and all 
that and before you ship a movie you can render it down to one.) 
Third parties can write additional effects and transitions as 
plug-ins; a friend's company (Buena Software, 
<http://www.buena.com/>) does this.

Is Ogg flexible enough to support full QuickTime-like functionality? 
Or is it more intended to be a media delivery format than a media 
authoring format?
