title: Synchronize Directory of Files Between Server and iOS Application
body: <p>I am building an internal iOS application (so - it won't ever be in the app store), and I need to keep a directory of content synchronized between a server and each of the instances of the iOS application.  This would be easy enough if I just wanted to delete and re-download this content each time, but I would rather use something similar to rsync to only download the elements that have changed.</p>
  
  <p>I haven't found any good way to utilize rsync.  I considered looking at Objective-Git as a possibility here, but at a quick glance it looked like there is still a lot of the support for remote repositories that isn't supported yet.</p>
  
  <p>As a final note, while this won't be in the app store, I will not be jailbreaking these devices and I would prefer to not rely on any private API's (although if there was an elegant solution that utilized private API's I might consider it).</p>
  
  <p>Thoughts?</p>
  
  <p>ADDITIONAL NOTE: This needs to be an isolated solution.  I won't be relying on outside services (like Dropbox, Box.net, etc...).  This needs to work solely between the device and the server (which is on a local network with the device).</p>
