I figure the easiest path into remote monitoring of EMC2 is to find or create a port of VNC to whatever platform you have. The tricky bit is to implement touchscreen functions and that usually requires some digging. VNC allows one to view and interact with the desktop on another computer and works across different operating systems. I know there is ongoing work to port it to Android. The only downside I see is that screen updates of the Axis graphics may be slow. One could switch the host running EMC2 to a different user interface to compensate. Porting VNC is the path I chose for my BestBuy Insignia 8" Infocast (Linux-based, Chumby-developed software inside) which I bought on sale for ca $100 last year. I should already be done, given the good work of others in the Chumby sphere, but my wife's rollercoaster health situation has slowed all my hobby work to a crawl. At least I get to use it as an Internet appliance while I dither. An 8" screen may be too small for you, but if not, I see that Chumby is coming out with their own version (ca $200) that may require less work to bring up either VNC or an X-server. The new 10.1" ASUS EEE Transformer is entering the USA marketplace ca $400 even as I write. It likely is everything one could want in terms of software and performance. Unfortunately, the price is based on its product placement as a combo tablet-laptop. Small touch screen monitors will likely remain costly in small quantities because of market economics. The trick continues to be to find and hack a consumer product that has a touch screen.
