Wow!

Software changes must be considered. We should ensure Jolla compatibility (to be able to use Alien Dalvik) and Harmattan compatibility. MeeGo Touch has to work flawlessly (I have a semi-working build of 0.26). Maybe I'll be able to help a little in the future about the sw. Applauncherd can be modified to work with gtk+ and other types of sw too. I have a building, but not working 3.0.3 build. http://talk.maemo.org/showthread.php?t=85716 I rebuilt it against latest meegotouch and will check it as soon as my n900 gets usable again.

You should talk with atilla77 and inean to bring qtm and qt components.

Qt5 should be introduced. Can it be built with qt4support as it was with qt3support?
Gtk+ can be updated at least to latest 2.x

Maybe we can take advantage of this: http://talk.maemo.org/showthread.php?t=89416
