Yesterday I attended the Melbourne Tandberg offices for an update on their new desktop video conferencing server/app combination known as Movi. Looks quite promising as a semi-managed solution to easily deploy conferencing across multiple desktops.
Limited to Windows XP only at this point in time, and with the proviso that the V1 of the product doesn't jump over firewalls... University of New England have been trialling the product and have had some positive results. Selection and configuration of webcams is left upto the end user, as is sound device settings but this seems to be a preferred approach to other applications which take over the multimedia subsystems and do some 'interesting' things.
Movi is based entirely on the SIP protocol stack, and can be integrated into multi-point mixed H.323/SIP connections using existing Tandberg MCU technologies, either stand-alone or built into an endpoint. There's still some way to go yet, the firewall traversal and Mac OSX support are notable, but this product has the possibility to make delivery of desktop video conferencing easier to support on a medium to large scale deployment basis.
