Wonderful writeup, hope you will consider doing the rest.
I've been thinking about doing a lot of these features in my install. It looks great.
Things I have been thinking about are:
Putting the LCD on a swivel mount, so you can angle it a few degrees side to side and maybe up and down as well.
I like how your screen folds down a bit when it comes out...that is what I am planning on doing, except having the dvd drive there, and not ac controls.
I love the cover over the screen. I think that is the best implementation I have seen yet, and I don't think that has to be motorized, but it sure looks cool!! I would like to do something similar.
How much space did the motorization take?
