I think that there is only 2 viable solutions for Trisquel:
1 - Gnome-Shell (the problem is that it may require a lot of work and Rubén is alone on this so it may not be a good solution for now). 2 - Mate (this would be the best solution because Ruben could re-use everything from all the old versions of Trisquel based on Gnome 2 and upgrade them with time.
