Assuming this means what I think it does, basically what we were postulating would be a great idea for a display extender for an existing empeg, has in fact already been done. Cool.

From the pics I see, the display board looks to be pretty thin, and roughly single-DIN sized. This would likely fit well where my clock currently is, which is where I would mount my empeg if I had the depth.

I assume that the raspi can be some reasonable distance from the board (10cm)? and the empeg itself can be Ethernet distance away, so that works (trunk mount).

Silly question, but can you show remote control of a standard (hijack'ed obviously) player? What does the boot sequence look like? What power dependencies are there (thinking "key on" in the car - does boot order matter? etc...)

What other specific hardware (ras pi, etc) is needed? I know, I know, you said you were writing it up... OK. Ill wait. Heck Im going on vacation for 2 weeks anyway. :-)

But please count me in line....
