How to easily receive notifications about GitHub commits in Google Talk

I have not found a quick way to notify my mates about commits on GitHub over Google Talk we all use. I asked about it on StackOverflow and they didn't have an answer. That's why I decided to create an tiny webapp based on Google App Engine to do that job. You can use it without registration and installation, just look through README to understand how it works and how you can use it. The job is in progress, but the basic functionality is there now, so you can receive notifications about commits. Source code is available from http://www.github.com/skible/gitport. If you have any questions, please feel free to contact me over email: sergey@skible.com. Thanks!
