From the research I've done, it looks like there are some issues with ReadyShare that make it somewhat impractical. What is your need to access the Kingston from the network? I usually recommend that people that want some kind of networked storage to stream to and from or to save or backup files get some form of dedicated Network Attached Storage (NAS).
If the above sounds like the kind of thing you're interested in or what you are attempting, there are a variety of NAS devices available for all experience levels. For example, Western Digital makes a Personal Cloud drive for less than $200, with 3 TB of storage. You could back up all the devices in your house and probably still have plenty of room for movies and music. WD NAS
If it's just minor file transfers that you're doing, this probably isn't necessary, and I don't want to try and make you go spend a pile of money, but I haven't had great experiences with any of the networked storage features that routers offer. If regular networked storage is something that you'd like, you are usually better served using a NAS, both for speed, security (most NAS with a cloud feature use HTTPS rather than FTP), and ease of use.
