Just had a look at their website....interesting product that could solve a few issues I have with iTunes libraries that are relocated to NAS on MACs (every so often on reboot the library defaults back to the local drive path - doesn't do it on windows PCs)!

I cannot see anything in the documentation as to whether the synch'ing process can be automated, do you have direct experience with this program? is it purely a manual procedure, or can it be set to update the NAS either on change of a library, or daily at a predetermined time?
