MojoPac
MojoPac is an application virtualization product from RingCube Technologies. MojoPac turns any USB 2.0 storage device into a portable computing environment. The term "MojoPac" is used by the company to refer to the software application, the virtualized environment running inside this software, and the USB storage device that contains the software and relevant applications. MojoPac supports popular applications such as Firefox and Microsoft Office, and it is also high performance enough to run popular PC Games such as World of Warcraft, Minecraft and Half-Life 2.
The RingCube website is currently forwarded to Citrix, which has apparently purchased the company and discontinued MojoPac.
