First, thank you for IPFS, it seems to be a definitely fun and perhaps promising idea
Any document is dynamic most of the time: its URL can change and so can its content itself. IPFS hashes solves the first part but how can we retrieve the latest available version of a document?
To the best of my knowledge, tree-based version control system (such as git) makes it trivial to access to parents of a document but further revisions are less easily accessible.
