It's currently in beta.
The feedback from the users at Reboot.pro has been positive and speed improvements have been reported, although I've not tested this myself as all my sticks were "lost" last month.

I put it in off-topic as I'm not sure how this benefits the Joggler community as we tend to use, Linux, disk images and multiple partitions, but it might come in handy for speedier swapping of files.
