I actually tried this at one point with a wall-mounted tablet before trying Sphinx. It is surprisingly good for offline, probably the best offline I've tried yet outside of dedicated software like Dragon. But it doesn't meet my open criteria, so I'm hoping to find something better.

I'll most likely give up on the requirements of it needing to be local and open, and use Sphinx for hotword detection to send the audio out to AWS for processing.

That's an awesome idea :) I haven't gotten around to playing with anything vision based yet. But I've thought of 'simple' projects like that, which would add a lot to the perceived intelligence. Figuring out the number of people in a room would be another useful idea I think. The AI could enter a guest mode when there is more than 1 person in the room, or when it detects faces that aren't mine, or something similar.
