OoVoo is a free, standalone desktop chat application that has both a text and video chat capabilities. It can handle as many as six people in one video conference as well as a dozen in the integrated voice chat conference. Users can drop in and out of conversations, and the video windows will scale with a similar effect to iChat's "swoop."
OoVoo also doubles as a video e-mail service. Users can send each other video messages as long as a minute in length that are available right in the application or via e-mail. Users who get the e-mail are also provided a link that takes them to a live Flash version of the video, so they can access it while away from their home computer.
