I still think you&#x27;re talking about a different, later thing. The client I&#x27;m talking about had no plugins and didn&#x27;t support video, but did support voip directly. It was actually a selling point at the time over MSNM&#x2F;AIM, iirc. You&#x27;re right it didn&#x27;t work on macs, or linux for that matter, because it was a native windows program and they never released a client for any other platform and there was no web interface to it at the time (but you could use any xmpp client with it, as you still can).<p>I&#x27;m pretty sure it was also before google even had TFA.
