s3fs is a FUSE filesystem written in python backed by Amazons Simple Storage service. Amazon offers an open API to build applications on top of this service, which several companies have done, using a variety of interfaces (web, rsync, fuse, etc). None of these companies offer a fully open source solution to using s3. This project is an attempt to remedy that.
