Create a BSD licensed drop-in replacement for rsync that can handle large numbers of files/directories and large files efficiently. The idea would be to not scan the filesystem for every client to detect changes that need transfer, but rather maintain some database that can be queried (and that also needs updating when files are changed on the server). See supservers(8) for some ideas of how this could work. Compatibility with existing rsync clients should be retained.
