 From the comments I read, I was under the impression that people found 
Kopete was still running even if it did not have any tray icon, so I 
guess keeping a window opened is not a requirement.

This can't be done because they are very different protocols:
- In the MI protocol the Kopete plugin passes the indicator description 
over dbus and a different process (in our case Plasma with the MI 
plasmoid) reads this and display it.
- In the systray protocol the systray icon belongs to the Kopete process 
and Plasma is just embedding it in the systray plasmoid.
