Detailed Design Docs

• FileEncoding?, explaining how we turn files into shares, with verifiable hashes; This is mostly concerned with chunking and Merkle trees.
• ShareEncoding?, explaining how we turn a chunk into shares: Reed-Solomon, FEC, that stuff

Outstanding Issues

• PeerSelection, explaining how a Tahoe node chooses which other nodes to use for uploading and downloading files (which raises some unsolved issues in balancing scalability, robustness, performance, and simplicity)
• ChangingFilesWhileCopyingThem? : what are the semantics of the "upload" action? the upload takes non-zero time: what happens if the file is changed during that time?
