As much as MeeGo has been developed it is no more than a very basic UI for the N900 and STILL requires closed source code to be opened if it stands a chance to address the N900 hardware.
Carsten posted on here only a few back and is pushing MeeGo hard without any talk whatsoever of the CSSU team and this made me sad.
Like it or not Nokia has done wrong in many peoples eyes and if the CSSU team are to be really succsessful it needs this code from Nokia UNLESS it can get away with reverse engineering of the closed components.
