Since we're on the topic, I need to report that I've managed to get
Speakup and Orca working on the same audio device using Pulse Audio for
the first time. I have not yet spent much time with this configuration,
but will certainly do so. It seems sufficiently robust to just possibly
be worth keeping.

Brief notes:

Orca with Speech-Dispatcher 0.8-5 as shipped by Fedora 20 driving Espeak 1.47.11-3 also packaged by Fedora 20.

Speakup using Bill Acker's espeakup compile for Fedora 19.

More soon.
