ooVoo is a multi-user video chat application which supports up to 6 users simultaneously. You can also send and receive video messages and files to other ooVoo users and even send video messages to users who don't have the software installed. Currently in beta for Windows only (Mac version due any day now) it's the new way to communicate online.
With ooVoo, you can connect with anyone, anytime, with video calls, video messages, phone calls, text and more. Use ooVoo to get face time with people you can’t meet in person (and save travel time and money!). ooVoo makes life easier and more fun.
