Wuala

Since I noticed Portable Java was released, I decided to try running Wuala ( http://wua.la ) from my flash drive. I noticed it doesn't want to use the java on the flash drive and doesn't want to setup an install folder on the flash drive. As far as I know, Wuala is still closed source, but I would think the exe could be modified to use portable java and run locally on the flash drive. Any thoughts?
