Hello,
for my professional use, I found the following tool for KDE 3.x 
administration : Kiosktool
http://extragear.kde.org/apps/kiosktool/
ftp://ftp.kde.org/pub/kde/stable/apps/KDE3.x/admin/

It looks like it is abandonned, but I compiled it and it works well for 
TDE 3.5.12 under RHEL6 ...

Could you add it to the TDE project ?
I found no equivalent tool for KDE 4, so it would be another good reason 
to prefer TDE over KDE4 for professional use !

Thanks
