Thanks! I'm going to look through this. Why is the serial connection so slow in your implementation? Is this a hardware limitation of your design? How could this be corrected/avoided?

Here's the question I have:

If the remote display is driven by the serial connection, how is it possible to also have buttons which send signals on the same serial connection? Why doesn't the display driver hardware monopolize the serial connection?

Thanks again. I'm definitely going to try to build one of these things. If anybody who knows how to hack the kernel is interested, maybe we can do this together.
