zoneball asks: "What would you use for a distributed file system for Linux? I have several GNU/Linix machines running at home, and wanted to be able to see more or less the same file tree (especially all the ~user directories) regardless of which machine I'm connected to, and where the traversal into the distributed file system space is largely transparent for the end-user. Are there any URLs or documents that compare the features, bugs, road map, stability of these and other distributed filesystems? Which offers the best stability and protection from future obsolescence?"
