Things like portaudio and MIDIshare never really arrived. (OK, I'm

The problems with Artsd blocking the sound server have become a lot less since 
sarge. I think because Artsd now recognises ALSA, maybe dbus helps this too, 
sorry I'm a little fuzzy on details. 

I think if we are making policy here, then setting ALSA as the basic sound 
system with JACK used in all cases where applications need to be able to 
communicate about audio signals in realtime, is the only sensible option. 
This will force everything else to be compatible, which is a Good Thing (TM). 
There are very few 'professional' quality audio applications that don't use 
these protocols. A/DeMuDi has enforced ALSA/JACK compatibility for two or 
three years now. 

The one thing that would be magic would be to get video apps to send and 
receive JACK transport signals. We would score major points if it were 
possible to sync totem up to Ardour or Rosegarden, particularly if it were 
possible to export the combined output to an ogg-theora file (or whatever).

I also think we should start considering 3d graphics support as a serious 
issue. I know this is largely driver-dependent. 3d graphics have some 
'serious' applications in the multimedia realm. If we are looking to the 
future this must not be relegated to 'eye-candy for gamers' - it is more 
important than that IMO.

I guess I'll have to give up on ever seeing OpenMusic in Debian, however.
