Hi cyberswat.
Thanks for a great module. We leverage Google Docs at Acquia, and we are starting to integrate the functionality into our intranet. The resulting module is being worked on at http://drupal.org/sandbox/cpliakas/1299122 and uses this one as the authentication mechanism. I have filed a couple of patches in order to get the authentication working on our environment, and I am interested in co-maintaining this module as it seems that there haven't been any commits in some time. Let me know if this is something you are interested in.
Thanks,
Chris
