The Oovoo video chat service is making a run at Google Hangouts this week, launching a new Facebook application that allows 12-way video chats with users on iOS, Android, and PC clients. The company is also releasing a new iPad app that allows you to host or participate in a 12-way video chat, but you can't view more than four friends at once – we're not sure if the iPad's screen size or bandwidth is the problem. Oovoo is also updating the PC, Android, and iPhone clients with a new UI: the PC client gets the biggest changes, but smartphone users will notice some less dramatic interface tweaks. The updates are free and available now, as is the new Facebook app.
