First posted over at TouchArcade.com, a YouTube video depicts what could be World of Warcraft running on the iPhone.

is an incredibly popular massively multiplayer online role-playing game (MMORPG) with over 11 million subscribers.

While there have been sketchy rumors in the past that this game could find its way to the iPhone, the video seems believable as it shows the game running within the Vollee client application. Vollee is a company that develops software to allow mobile 3G phones to play CPU intensive PC applications over the network. Their first demonstration in 2008 showed Second Life on a mobile device. The software works by essentially streaming video of the game rather than rendering it by the handset itself:

The companys VolleeX engine adapts applications for screen size and key layout, and then streams the original application to mobile devices. Vollees interactive video streaming platform optimizes compression to minimize bandwidth requirements and also leverages the 3G mobile networks in such a way that gamers can easily and smoothly navigate virtual worlds. Vollees technology is also extensible to fast paced, high quality video games previously impossible on mobile.

Vollee has also previously announced upcoming iPhone support as well as a partnership with ActivisionBlizzard which would make this client a distinct possibility. The company, however, has been rather quiet lately and their website is currently not resolving.
