windows 7-like application docklets

Has anyone developed, or planning to, a docklet that emulates the newish feature in Windows 7? I'm talking about the application icon that serves as a window manager.

I haven't actually used Win7 yet. I'm assuming it's a launcher icon that turns into a manager when the app is opened.

I'm not suggesting copying anyone.. but a semi-good example of what I mean is like combining a regular app icon for a launcher with the Tasks docklet made by albeik on Dockex.com.

I hope I'm not asking a lot cause this would be pretty cool! Thanks!
