ooVoo Video Chat
ooVo is a free video chat application for Windows and Mac. It allows you to have online video meetings with up to five people — unlike Skype, where you are limited to two participants in video meetings.
The Windows version of ooVoo has some nice features. My favorite is that it allows you to have a video chat with people who don’t have ooVoo installed. You send them a “video call link” though email or instant message, and they can chat with you via a web browser. Another nice option (again, only on Windows) is that you can “minimize” the ooVoo application window to the sidebar. This frees up your desktop so you can perform other tasks while still participate in the meeting.
