Ah, OK.

I did read the spec for Ogg once. I don't remember it now, but it seems 
a simple enough format without much overhead.

In particular, you're supposed to be able to take any valid Ogg file, 
slice it in half at some arbitrary point, and the two halves are ment to 
still be playable by any compliant player, even though you just sliced 
right through the middle of some data structure.

While we're on the subject, Vorbis is ment to support "bit peeling", 
where you can take a Vorbis stream and "easily" strip off parts of it to 
yield a valid lower-bitrate version without having to actually transcode 
anything. Sort of like progressive JPEG - the data is arranged in such a 
way that it's easy to quickly discard low priority data to lower the 
bitrate.

How well any of this works in practice? I have no idea! ;-)
