h1. Watcher prototype
The cache file structure store all the hashes of the shared files. If a file is added or removed from a shared directory (or a subfolder) it should be added or removed from the cache.
As far as I know there is no way to watch changes recursively of a folder tree. The QT class _QFileSystemWatcher_ cannot watch recursively.
The only way to synchronize is to periodically scan all the shared data and compare to the cached one. It can be a bit CPU consumer so it should be done with a low priority thread and maybe with a pause between each file hashing.
h2. famd
On Linux it exists a file monitor named _famd_ ... maybe it can be a solution for the Linux based platforms.
h2. FindFirstChangeNotification
On Windows a directory and its subtree can be watched, see : http://msdn.microsoft.com/en-us/library/aa365261%28VS.85%29.aspx
