Ok, I misunderstood what you said in #1, then.  I agree, a dirt simple audio
player would be easy and beneficial for anyone trying to migrate away from
audiofile, etc.

Main loop integration for such a case is fairly easy (in pseudocode):

gst_play_audio_file() {
  set up pipeline
  add idle handler to main loop
  set pipeline to PLAYING
  return object
}

idle_handler() {
  get bus message
  handle bus message
  if in error state, fire error signal
  if done, fire done signal
  if not done, re-add idle handler
}

In this case, gst_play_audio_file() returns immediately, and the app can wait
for the "done" signal if it wants.  Or, there could be a separate waiting
version.
