i'll probably implement it for xfmedia first, and then do xfdesktop.  
maybe.  we'll see.  depends on my mood.

yeah, i've already skimmed through it, though i could use a refresh.  it 
seemed pretty easy to understand the first time through.

indeed.  xfdesktop's IPC will mainly be used to remote-control xfdesktop 
from the commandline.  if d-bus isn't available, then that just won't 
work.  oh well, too bad, so sad.  i probably won't require d-bus for 
compilation either, at least until/if we decide to make it a 
desktop-wide dependency.
