Straying from the path of other video chat products, Google Voice and Video uses a proprietary plug-in instead of Flash. A miniscule download of 2MB supports Internet Explorer, Mozilla Firefox, and Google’s own Chrome on a PC as well as Firefox on a Mac. Details have not yet been released on support for other platforms, such as Linux, but ports for them may come later. Google Video and Voice made its official public debut at midday on Tuesday, November 18th. Now that Google provides Voice and Video, users have access to a vast array of tools with one login, including email, voice, chat, and soon even SMS. If Google ties in Youtube and Google Docs better in the future, the Google account will be nearly unstoppable.
Google’s Voice and Video is quite simple to use. When the option is available, a "Video & More" button is shown in the chat messaging window. Once selected, the plug-in will be installed and immediately accessible for video calls with friends.
