Looks like games are coming to Google Plus in this announcement. What makes this of interest to us is that they will be having a developer's program which you can read about here. Eventually we should get additional tools, like dice-rollers, that will enhance Google Plus for table top games.
To me the Old School Renaissance is not about playing a particular set of rules in a particular way, the dungeon crawl. It is about going back to the roots of our hobby and seeing what we could do differently. What avenues were not explored because of the commercial and personal interests of the game designers of the time.
