Ok, short answer to long mail - I'm at work so I shouldn't be reading d-d-l :-) XESAM is *exactly* what you talk about. See http://xesam.org. If you are interested I suggest you read the RC1 spec an give your comments on the xdg list at freedesktop.org. I given a small XESAM status report somewhere in this thread. Should be easy to find. Cheers, Mikkel
