Google Talk MultiMessenger - A simple TrickWe've used MultiMessenger Like Gaim or some other thirdparty clients like that to access same IM(or many) network through many user IDs at the same time and from the same computer. Normally, we're not allowed to do but with the help of some third party multi-messenger, we can access more than one account or different IM account from single interface.
In Google Talk, for this multi-messenger purpose, there is a little trick. I've two Gmail Ids and while One is Logged it, to connect from another ID, i apply this in run(click Start->run):
drive:"(Google Talk path)" /nomutex
"c:\Program Files\Google\Google Talk\googletalk.exe" /nomutex
and second instance of Google talk will start allowing me to log in from there, second time from the same computer.
Hope that helps to people who has more than one Google ID.
