 ## Detailed Design Docs
  * [TahoeIssues](TahoeIssues)/FileTree, explaining how mutable, shareable, private directories are implemented (which requires interesting crypto)
- * [TahoeIssues](TahoeIssues)/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)  
  * [TahoeIssues](TahoeIssues)/FileEncoding, explaining how we turn files into shares, with verifiable hashes; This is mostly concerned with chunking and Merkle trees.
  * [TahoeIssues](TahoeIssues)/ShareEncoding, explaining how we turn a chunk into shares: Reed-Solomon, FEC, that stuff
 
+## Outstanding Issues
+ * [TahoeIssues](TahoeIssues)/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)  
+ * [TahoeIssues](TahoeIssues)/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?
