The thing with D-Bus is that it is not network transparent. While I do
like D-Bus a lot it is thus not really suitable for the PA case. The
native PA APIs are all network transparent, and thus D-Bus is not
really a suitable replacement I would say. And carrying two IPC APIs
around all the time doesn't strike me as a particularly good idea.

Sometime in the far far future I will replace the PA native protocol
by something based on D-Bus-via-TCP together with RTP for the audio
data transfer. But that's something for the future.

Of course, I won't stop you from hacking up a D-Bus module.
