we're not expecting it for 4.3; we want to trial it out before committing to 
BC guarantees which means trying it out on various applications and making 
sure it provides for our current use cases.

a d-bus driven replacement for the xembed system tray icons. it is data 
centric rather than display centric, allowing for more information about the 
icon (e.g. it's activity status, category, etc), multiple views on the same 
icon and moving as many of the visualization decisions as possible to the 
host.

they are faster (appearing instantly from a user's POV in the system tray) and 
look much more native (whatever that means to the host system)

yes ... in 
playground/base/plasma/libknotificationareaitem/knotificationareaitem.h

it falls back to an xembed icon. in fact, if the dbus service appears and then 
disappears, it will toggle even between the two modes. it does this by having 
a KSystemTrayIcon as a member of the private class and instantiates that when 
needed. this way, should we get to the point where there are no xembed based 
implementations in wide use we can remove it but in between now and that 
potential future we maintain seamless compatibility.

(this is why i really wanted to have this taken to k-c-d before starting 
wholescale porting of apps. :)
