Hehe... Well deskbar is not actually my child. It's Nigel Taos, I'm just
the one raving about it :)

I absolutely get your point. Putting a daemon on the bus might be
overkill. I have no idea on how much overhead this gives. Benoît Dejean

"Is deskbar-applet designed so that other programs in other languages
can make searches ?"

 - and I just grabbed my old dbus idea an posted it :) I think it allows

it comes at a price... That was also why I would like to discuss it.
