Great work. Planning to read about it. I, and I am sure others, are continually intrigued about this space and I hold out hope that the definitive solution appears soon (along with the solution to micropayments !!).

On a slightly related note, is anyone interested in having a discussion about how to layer on top of all these "drive" systems a `HDFS` like drive that would have n block replication across different sources, and trying to interpret any given source (dropbox, hyperdrive, google drive, etc..) blocks to make sense of what is being stored there would render the person confused?
