SAN FRANCISCO -- RealNetworks Chief Executive Bob Kimball took the stage at the Dive Into Mobile conference to give the first public demonstration of "Unifi," the Seattle company's new cloud media service.

The service will "catalog" users' media collections and make them available from any device connected to the Web, eventually.

"We actually show you your whole digital life and let you work with it," Kimball said.

Initially the service will handle music and photo files and work with computers and Android and iPhone devices. Later it will work with BlackBerry and Windows Phone devices.

It also pulls photos taken from mobile devices into the cloud repository, where they're available from different devices.

It will launch in the first quarter, Kimball said. The basic service will be free but have limited online storage. Additional capacity will be available for the price of "a cup or two" of Starbucks beverages per month, he said.
