Hey guys,
I've had a little side project I've been working on and tied a bunch of it together in time for presenting it at a conference this afternoon.
I did a bit of reversing of the WU-1a and the WMAU app, and managed to get it working with my D800. I've also got some remote control pieces working over wifi with libgphoto in linux and in a little python utility i wrote.
I'll drop the links now and will do my best to share all the code and circuits in the next few days (perhaps on the nikonhacker wiki).
my slides (though they don't stand well on their own): http://goo.gl/5530H
