Gtalkr, Web-Based GTalk Client:

A few weeks back I introduced you folks to Meebo, a browser-based IM aggregation client that leveraged technologies collectively known as AJAX. Now meet Gtalkr, a Flash-based implementation of Google Talk. I have been playing around with it for a few days, and as a Mac user, I can finally enjoy the GTalk IM Service. It is fairly simple product to use. Go to this website, use your Gmail ID and log in. Nothing to download, nothing to install. But ease of use is not the only thing. In many ways it is like GTalk plus. (I wish it looked prettier, but it works nicely
