iPhone unread dots on homescreen on web app icon

I'd like to know if it is possible to have unread dots on a icon of a iwebkit-based webapp.

I've read this but its for native apps. Is it possible to simulate this with javascript or something? iPhone unread counts on tabbar

No, only native applications can do this.
