Indeed. When thinking about the recording use cases, I could come up 
with a few interpretations:

- Record one media stream, as it arrives (the "voice mailbox" concept)
- Record a conversation: Outgoing and incoming audio and video in an 
1-on-1 or 1-on-N context (typically as permanent records of a meeting or 
conversation)
- Record the application screen as presented to the user, together with 
the audio tracks as presented to the user's audio device, but don't 
bother with incoming audio from the user at all (game recording, for 
instance - the "WoW movie" kind)

In each instance, recording technology might include recording:

   - As one track, somehow mixed, ready for playback
   - As multiple tracks recorded separately within a container that 
requires special playback devices
   - As multiple tracks, recorded separately to separate objects
   - As streams sent to some remote recording entity, that may choose 
one of the options above

I'd be happier about discussing which ones of these people find it 
critical to support before we dive into figuring out how to support them.
