During those 12 weeks of my Google summer of code, I have hacked mainly on 2 gnome project which are gvfs and libgdata.
Concerning libgdata, I added the google documents service and it's now in the master branch, it's functional even if there are still a few bugs.
As far as gvfs is concerned, I have an alpha version of the gdocs backend which isn't really usable for final users yet, but don't worry I am going to make it working well in the coming weeks! All the functions are implemented, I need to stabilize it and optimize it in order to hopefully get it merged in gvfs.
I have also worked a little bit on nautilus to support the new backend (almost nothing).
