Ok, thanks for the explaination. Interesting that the file browsers are 
using it. I found a bunch of bugs where other software had to be updated 
to handle the new type (as a literal, not a parsed description) but not 
the original reasoning for it.

Note that we are using audio/x-vorbis audio/x-speex and video/x-theora
in the RTP payload drafts. That's a different container with only one 
media type per stream, and it's important to know the actual codec, not 
just the disposition.

Haha, oops. Sorry I didn't recognize your nick.

Thanks for the link. That seems a reasonable abuse for video rss 
feeds, and I guess you could use media="screen" for slides, but 
what do you do for audio?

Yes, "folksonomy" tagging would work about as well here in practice. 
Will be interesting to see if a standards-oriented body like the IETF 
ever ratifies something like that.

No, it doesn't help. The original complain is based on Windows 
Explorer only associating applications with file extensions. The
problem is much more tractible if you can do even file magic
identification. I don't know if they've tried to address this in vista.

In the past we've suggested writing a dispatcher application to handle 
this: associate it with the .ogg extension, and it checks the file and 
opens the app of choice. Supposedly someone wrote such a thing (called 
Ogg Prak) but we don't have the source. It may have been vapourware.
