This is mobile videoconferencing brought to you not-quite-yet by Vidyo. Its VidyoMobile software has been demonstrated at various venues this year starting with the . The buzz around the product got another boost this week at Interop 2011 in Las Vegas, where it was formally announced and it also won the Best of Interop Award in the "collaboration" category.

The product is essentially a port of Vidyo's existing Mac/PC client to iOS and , for and tablets. Previously, the vendor extended its software development kit to allow mobile devices to join a videoconference of participants using PC-based and room-based video systems.

With VidyoMobile, mobile users can conference with other mobile users over Wi-Fi or connections.

In the port, the full client loses a few things along the way: currently only four parties can conference, and the sharing is limited to video (the full client lets parties share anything else such as email and apps, according to Vidyo).

But it apparently has not lost battery efficiency. In tests by the vendor, VidyoMobile on the iPad 2 "lasts six hours with straight videoconferencing," says Young-Sae Song, Vidyo's vice president of product marketing. Perhaps optimistically, he added, "No one is going to videoconference for six hours."
