Just in case you guys did not know, for those of you who like to use Google Talk but end up using Gmail for the Invisibility ( aka feigning invincibility) factor, the Labs version of Google Talk allows for you to go invisible.And no, it doesn’t yet have the Video chat capability that came in Gmail a few weeks back. Seems like the Labs Edition has been around for a while but I noticed it just recently. Check it out if that is what you need and let me know how it goes. I found it getting  disconnected and reconnected on its own quite a few times.
