I recently needed to do this for google, but i wanted the rendering time, and delivery of the page to be under 500MS, so i hacked up something that works with expressjs
It uses phantomjs but removes all the styles initially so the rendering time is much faster. (my ember app was averaging 70MS to render, but i prefetch the page data)
