nextaction more Ajax goodiness

This is cool. Using newly-minted SPADE (Single Page Application and Development Environment) technology, which translated from Geeklish means "entire application in a single web-page". NextAciton is a AJAX-style to do list. What cool, is that you can interact with it and then save it, email it to friends, commit it to CVS etc etc. Using the nice feature that "Save As.." option in browsers will serialize the current state of the DOM tree (rather than the original loaded page). Just save the link above as "Web page complete" and then reload it into Firefox. How soon until the rest of the office apps get a similar AJAX treatment ?
