[feature reguest] Possibility for an optional replacement of amarok tray in third party aplication

[Stilitiano]

I've started using  Kirocker Music Display for Amarok ( 
http://www.kde-apps.org/content/show.php?content=52869 ) and thought it 
could also be a good replacement for standard amarok-tray but as 
developer of Kirocker said when I asked him about implementing this 
feature "The problem is that when you disable the Amarok tray icon, you 
can't hide the Amarok main window anymore. If you close the main window, 
the entire Amarok application quit. You have to have the Amarok window 
in your taskbar."

It is true so I thought that Amarok should allow other applications to 
act as amarok-tray. Then Kirocker could have in it's properties "Let 
Kirocker be your standard amarok tray application" or "Set Kirocker as 
default amarok tray", whatever. Advantages?

- better Kirocker =)
- possibility of better integration plasma with Amarok (

- possibility of better Superkarramba widgets for Amarok

I don't have any idea how to implement this (API, configuration file to 
modify by third party applications?) but IMO it is wort to implement. 
What do you think?
