Something concrete would be good to know. I'd be happy to pay someone else to make me one if the plans are released, or do it myself if it could be a kit or something. I'm great with soldering kits and instructions, but anything requiring the reading of electrical schematics or getting non standard parts, I'd need some additional guidance on (or pay someone to do it for me).
It is a really important feature of the Mega SD to me, and one I'm anxious to get access to.
I'd gladly pay for a PCB fabricated by TO and a bag of stuff to solder-by-numbers to it, even if I need to get the other stuff besides the PCB myself.
