FINALLY I have enough total useless garbage posts to post here - "thanks," XDA.
Been using the most recent build (omni-4.4.2-20140402-i927-HOMEMADE.zip) for a few weeks now. Mostly works well, with a few caveats:
GPS does not work very well at all, by default. I couldn't get it to function at all, in fact, and I had to install GPS Tools to get any functionality.
I've had a few crashes, one which I can reporduce:
I flip open my keyboard to write text messages, which rotates the screen. If I flip the keyboard back in after I tell the phone to send the message, but BEFORE it actually gives a "sent" result, the phone will crash. This means I've had to be much more careful when sending texts.
