I packaged up an initial version of plasma-icontasks,
http://kde-apps.org/content/show.php/?content=144808
I'm personally not entirely able (time mostly) or interested in
maintaining it officially. Hopefully, now that the initial work is done
for you, maybe taking it over would be easier. ;)
.spec srpm here:

I'll put some builds of this into kde-testing shortly to wet your appetites.
