I wrote a sortof program that makes kindle as a second PC screen. The way it works is that it captures the screen on my computer, and then sends to kindle, and kindle then shows the image. It's like a media streaming system. The response time is terrible right now, it has a delay of about 0.5~1 second. I still don't know where the bottleneck is. The image I send over is zipped, the size for the full 800*600 screen is about 20~40k, and I only send over the difference between two consecutive screen shotshots, which is much smaller. Maybe the big issue here is finding out the updating area. Currently I don't have a good algorithm to get that out, so most of time, I guess, it's updating the whole screen.
