^^^ this does all the work. Apache Licensed. The guy who wrote it is excited about contributing it to the project. It took me all of 2 minutes to integrate into a standard DroidGap-based app. On my Galaxy Nexus I was able to get 5 simultaneous touches being tracked perfectly. Would need a little cleanup JS-wise. Also gives us the excuse of adding touch tests to mobile-spec. Pretty awesome..
