Hi,

   Thanks for the links and information!

   About the native notification API: I've asked around and it seems 
that dbus is good enough for us.

   One more question: Do You think it would be a good idea to include 
gumd in the standard ks file for images building?

Best regards,

Krzysztof Sasiak

So would such solution can help you more or dbus notifications are enough?
