Thanks, this is very helpful Chris. I guess <figure> it is then. I guess this will run past the filters too, so frontends can use it or ignore it as they wish.

re offsetting - is there any real concern that any modern implementation of a media player can not deal with offset? How would we code the offset?

re format - I do see the concerns re patents etc, but does this really affect anyone who distributes e.g. mp3 files? I would think the problem is not with files but with players. And as we would use only build-in players (either via rendering engine or external) it is also of no real concern to us either, is it? Mind you, as a non-American I find the matter more quaint then concerning as these things (software patents) do not apply here really. 

So, anyway, I would suggest that we allow - just as with images - a variety of file types and just hope for (gradual) expansion of any deficient media players (here mp3, ogg and aac) - and steer confused souls towards ogg.
. I would guess as long as people are sensible we will not have to deal with really strange codecs anyway. People like those lot who insist on producing RTF marked up modules will not listen anyway - even if we tell them that we do not support x,y or z. "But it works on frontend ....!"
