CloudFTP is a proposed device to wirelessly share any USB storage device with an iOS or Android device. By creating an ad hoc network (or joining an existing one) it allows for the sharing of just about anything. The Kickstarter
has garnered more than twice its intended goal but there's still 36 hours to go if you're wanting to get a deal on this little guy (will retail for $99 but on sale here for $69). It's a pretty brilliant little piece of technology and, I imagine, will improve as the web software / app comes together better.
