Have you used Google Local Chat?

To add the Local Chat feature to your personalized Google homepage, first log in to the Google personalized homepage and select "Add Content" at the top left corner. Then click the "More" button below the sidebar, where you will see "Local Chat." Simply click "Add" to include it. For simplicity, first log in to your personalized homepage, then directly use this link: http://fusion.google.com/add?moduleurl=http%3A//bas ... ems%3Foid%3D6247163394761210999. This will suffice.
