This is a big one for me as well.
There's more than just controlling the Brick with controls on your screen. I'm thinking about using it to control a small scene with different motors firing up at different moments, with the App just running a script, or perhaps even responding to sound, who knows.
There's probably people out there that can come out with some interesting stuff. Getting the Community to work for you is probably the best way to skyrocket publicity and possibilities for this thing.
I'd appreciate it if you'd consider this.
