Porting Objs jQuery Employee Admin Demo to Native is a good idea. I'm not working on that for the moment. Please just be sure to use
sources from my Github, it has slightly changed when I worked on the jQuery Mobile demo.
For StateMachine, for what I see in what David made seems, it looks like finished. He even has added unit tests. I do not have time to test it for real but it looks like finished. Note that I never wanted to use E4X in my project you just had a look at sources when they were first converted from AS3 to JavaScript. This was just the original E4X AS3 code not JavaScript.
