I was thinking the entire utility would exist / be accessed via the KDE systemsettings (at least for kde users).
The layout of the various modules in the systemsetting GUI is controlled by a bunch of desktop files... awhile ago I tried to hack together a "solution" to unify the tools from PCC into KDE's systemsettings.. it was pretty ugly, but you can download it if you would like to take a look at how I added them:http://dl.dropbox.com/u/2425248/kde4-pcc-systemsettings-addon.tar.gz
(..the idea was stolen from a mandriva spin-off, BlackPantherOS)
The tar contains a read-me file that explains how to "install" the files.. desktop files are used to create new tabs in the systemsettings GUI, as well as headings, and sub headings, and icons / links. For this project the actual KDE Control module (KCModule) was just a short python script to launch the apps that are a part of PCC.
IIRC I had to restart the systemsettings GUI twice before the new files were picked up by it. A few of the tools that I created links to when I put this together now no longer exist or have been renamed, but it should give you some ideas as to how this could work.
If I can explain further, let me know.
