Portable Applications

I am always on the look out for small tools that allow me to work more efficiently and effectively. The website Pendriveapps.com has a large number of applications that fit the bill plus some applications for having a little fun.

MojoPac

MojoPac is a virtualization tool that can be put a various portable devices like an external hard drive, thumb drive or iPod.

Has anybody used the tool? What do you like about? What draw backs have you seen?

From what I have seen and read on the website. It appears you don't need a second license for the OS but you need additional licenses for the in software you install. The MojoPac website does not make it clear if additional licenses are needed.
