Of course I don't know what the implications of suggesting that are yet :> The problem with doing a directory scan is not so much difficulty as efficiency. If we're using DBus, we could perhaps provide means whereby efficiency could be improved. Perhaps I should try to find some time to put the effort into learning more about DBus. That or we could seek to pull RML or Kay Sievers in - they know a fair bit about it already.
