why not just turn the status bar off (which you can) and use the footer with the appropriate HTML to do the magic you need?
It's easy to customize static elements in AIM, but not so simple to add custom dynamic elements. AIM does provide a JS API, but it's really only useful for interacting with existing AIM elements, not creating new elements. These days, most websites include a notification center. Think about all the badges and alerts you receive from Facebook, etc... When you click on the alert, it displays all your recent alerts. AIM doesn't have this capability at present, so this puts us at a competitive disadvantage when developing applications for clients who may expect it.
The Status Bar seems like a logical place to add a notification center and other types of dynamic widgets. Additionally, we should be able to remove elements like "Business Space", that are not relevant to end users.
