It would make sense to build a light-weight component set for Flex, which could be used for rendering Flex apps in HTML5 later on. The approach could be based on the UI/component implementation OpenLaszlo has (which provides cross-compilation features for ActionScript and JavaScript, check this demo): http://vimeo.com/32853986 HTML5 version http://www.openlaszlo.org/lps_demos/demos/lzpix/app.lzx?lzr=dhtml SWF version http://www.openlaszlo.org/lps_demos/demos/lzpix/app.lzx?lzr=swf10
