Agreed, that remote audio already exists, and works fine. However...there are disadvantages to using a system that doesn't ride within the X protocol. These include:
1) Prolifiration of APIs
2) Complexity of configuration (particularly firewalls, etc.)
3) Most importantly, strong synchronization. Unless the audio and display information travel through the same stream, and go through the same event handling API, there is no way to guarantee tight coupling(e.g. <20 milliseconds) between audio and display events.

3) MAS (www.mediaapplicationserver.net) does this. There's no need to
reinvent the wheel, MAS integrates with X already. I don't think it
needs to be part of X, synchronization issues for audio/video
aren't really the domain of X.
Another nice feature of MAS is that it allows you to transfer compressed
audio (and in the future video) through the network that gets decoded on
the target box.

P.S.: I don't have much experience with MAS, it just seems to be a
project with exactly the goals needed for network transparent sound and
video. I don't think that should be integrated into X.

Very interesting, and they look like they are doing things the "right way". One thing I couldn't tell from a quick scan of their docs is whether it is easy to synchronize sound with regular graphical events, such as the visual cues associated with selecting an item, etc.
