1.  Could decide whether to submit a form using AJAX or HTTP on a form-by-form basis

2.  Sometimes when submit a form, may want to go to an arbitrary "page" (i.e. already loaded subpage).  But seems can't do this since action determines both the AJAX call and the page you go to next (if i understand things correctly).  May be better to separate these things into separate variables.

3.  Formally exposing a callback from ajax form submission would also help (could take place of 2).  If this is already possible i haven't been able to figure out.

Also currently seems that if post to a random url, JQM will display the last subpage on your main page, which i assume is a bug.
