Thanks for the mention @jadedoto. You're correct, we're not running Android on our screens, but there is an Android port for MT4j, the Java multitouch framework we use: http://www.mt4j.org/blog/index.php?entry=entry110404-105831 If this Android x86 port comes further along (and there's some way to do remote administration for Android), maybe we can start developing for Android first, and porting that over to the large screens.

On the hardware side, one of the unfortunate limitations with most large touchscreens in that price range is that they only accept 2 touchpoints. For most applications, that's sufficient, but Martin mentioned that one of his goals is to enable multiple users to simultaneously interact. While the opportunity for that is a bit limited on his Acer screen, the larger screen size alone does make it easier for two users to view the screen simultaneously, and it's easier for them to alternate in usage without passing the screen back and forth.
