Roadmap

The goal for this code base is to come up with a good and simple solution for resumable file uploads over http.

• Defining a good http API
• Implementing a minimal / robust server for it
• Creating an HTML5 client
• Setting up an online demo
• Integrating Amazon S3 for storage
• Creating an iOS client
• Collect feedback

After this, and based on the feedback, we will continue the development, and start to offer the software as a hosted service. All code will continue to be released as open source, there will be no bait and switch.
