XP Taskbar Toolbars?

[iCEhOT]

Had an idea, but cant seem to find ANY information on it anywhere.

With so many people using applications like desktop sidebar, or smartbarxp - which are both great programs, it suddenly struck me, for some people who want to make desktop sidebar into something like the original task bar, with a start button and programs list etc, but also all the other nice added features. Why not just use the original taskbar that comes with windows, and create active toolbars for it (like windows media player, or zonealarm can have stuff in there).

If they can do it, it must be possible, to add system monitoring, weather reports, longhorn style clocks, or any other active content.

Dunno if I'm searching in google wrongly, but searching for "XP Taskbar Toolbars" or "XP active toolbars" etc etc, seems to yield no results. Is there any reason no one has ever made any decent toolbars?
