The site for all those questions is right here. I'm rather out of the loop with regard to the latest tech wave, but I was able to use the information there to cobble together a home brew Cintiq from old Penabled tablet PC parts with great success. I made a how-to about converting a 14" Toshiba Tecra M4. The video driver boards have made a leapfrog or two since then, and I'm pretty sure you could find something to drive a modern screen. However.., I don't know what the status is on re-directing Active Electrostatic digitizer tech. I was using the waxbee code one of the tech geniuses on Bongofish came up with to capture input from the Wacom EMR board which came with the Tecra. But I'm sure your questions would be responded to.
