Machinations with func_devstate is the droid you're looking for.
However, there is an issue with the current use of state_interface in
app_queue where it is required to have a '/' character in it (obviously
would for Channels, but custom device states are of the form
Custom:yourdevicestate).  I've worked around it, but I've been meaning
to file a bug report about it.

Anyway, have a look at that.  It is being used successfully by us (in
1.4, with Russell's backported func_devstate and custom changes to fix
the aforementioned issue).
