I would simply offer it in existing shortcut kcm (as checkbox-option to 
turn on and off for just extra secure case if something should 
conflict') and map to exisiting shortcut.
That way its not tied to anything, it's flexible and uses exactly the 
ksuperkey mechanism.

When we tested distros in BCN back then I noted down all of the system 
(other than rebecca black :) had it mapped.
