Object PATCH for efficient Swift based Cloud-Sync services

Hello everyone,

I'm taking a seminar in advanced storage systems and my assignment was to experiment with new functions for Swift.
My idea was to allow Swift to host efficient cloud-sync services (similar to Dropbox and others). Currently, an attempt to implement such services will result in a waste of bandwidth when objects are changed. This happens because on each change, the entire object has to be re-uploaded. Therefore, implementing a "PATCH" method for objects, allows us to send only the change and not the entire file, saving precious bandwidth.
I have also implemented a basic client based on FUSE. Combining the two, one can "mount" a Swift container onto the filesystem and any user-land application can work with those objects as if they were normal files.

I have implemented the necessary methods, and the result seems to work well. I was wondering if the community is interested in this function, if so I can describe my design and changes and create a pull request.

In addition, a friend that is taking the seminar with me is implementing a method that allows objects to be downloaded via BitTorrent (similiar to S3 functionality). If that's something that the community is interested in, he will be glad to elaborate further.
