Converting any window into plasmoid.
Embedded Win is an applet that allows you to convert any running application into plasmoid.

How to use it:

Just add "Embedded Win" Widget the usual way
right click somwhere on the Widget area
select the win application to embed
Enjoy :)

Issues

Currently it works using XEmbed protocol and therefore have lots of problems:

    You can't rotate these plasmoids and they don't work correctly with ZUI (however the latter can still be improved a bit)
    
    Z-order of plasmoids is not respected (i.e. in case you have several overlapping plasmoids)
    
    Switching between Desktop and Dashboard is not very smooth: embedded applications are only repainted after several-seconds delay
    
    There is another problem: currently you have to manually re-configure all window-embedding plasmoids after restarting plasma. For KDE applications this can probably be partly fixed by using KDE session management, for other applications one can allow the user to setup command line of the application to start.
