Sencha does this for enterprise apps too. For publishing, I wish RSS feeds had taken off. Would be great to visit a site and see that I could just subscribe to their RSS feed and see it in my own reader app.
The loss of RSS just still blows my mind. I still get my podcast with it but sad to see RSS to be relegated to obscurity when it started out so strong. The issue was the implementing it was "too much trouble" with the public.
