yes, that would be one application, but it would also be possible to use
this plugin for audio retrival.  All we have to do is when a client
requests that the audio be returned to it in file /some/place/for/audio
then we reconfigure the modules audio plugin with the AUDIO command to
the plugin so that it sends audio to that file, and then when that chunk
of text is done we reconfigure audio for that module back to the
default.

 yes, we need to extend the client api, and I'm not sure how best to do
 that yet.

 This plugin does make our part of audio retrieval pretty easy though,
 because all we do is reconfigure the module's audio settings before and
 after the message where audio is being retrieved.

hopefully this makes it clearer how this plugin allows for pretty easy
and clean audio retrieval.
