Another feature that I could see being beneifical is not only being able to set up rules on what is cached to the mobile client device as well as rules on when it should be deleted.

Example:
I have one device that is on a weak WIFI signal that streams content from a central NAS. I'd love to be able to cache all new tv/movies that is added to the NAS on this device. Once it has been flagged as watched in the SQL database (whether it be from the cached device or any other device) the tv/movie is removed.
