yes, we could use that .. it's what KDBusService essentially does. however, 
that tends to, ime, lead to unnecessarily fragile code as classes like 
KDBusService usually end up accumulating odd bug fixes and work-arounds for 
edge cases.

it's one line of code to use KDBusService, and more than that to use 
isServiceRegistered directly. the downside of KDBusService is under Frameworks 
we'll pull in one more library .. though a very small one with no deps.

i really recommend KDBusService.

i'd prefer something not over dbus tied to one window manager if at all 
possible.
