I have a handful of websites pinned to my Windows 7 Taskbar using Internet Explorer 9. This includes Outlook.com, work hosted Outlook webmail, Google Reader, Facebook, and Yammer.
As long as the sites are open, Outlook.com and Facebook both have the lovely feature of displaying a badge on the icon when there's unread messages. It would be great to get similar functionality on the other pinned sites as well.
Is this something that can be hacked or built from my end, or does the website have to push a new icon to me everytime it updates?
