ooVoo is a multi-platform video conferencing/chat application that boasts allowing up to 12 simultaneous video streams.
Unlike Skype, ooVoo doesn't make use of peer-to-peer connections, instead relying on some kind of cloud configuration. Apparently because of this, ooVoo's CEO has stated that ooVoo isn't typically used for "scheduled international calls or professional meetings," instead focusing on casual users. Nevertheless, the Washington Post claimed in 2011 that ooVoo had been approved for official communications within the US House of Representatives.
We tested ooVoo as a 3-person team with one person in Weimar and 2 people at separate locations in San Diego.
