No, sure, you should not do anything because others do it. But on the other hand, if others do it, why don't you? Better copy a good idea than be stubborn for ever. And yes there is no such thing as a killer app, but in my opinion it's the user experience. It's so much better when your system keeps track on shared network resources. But first things first,I will try to make the first option work, which was the use of a remote notifyfs server. This works of course only with linux like systems: so not when the remote server is a Windows server. I know that SMB (2?) has the ability to send a SMB2_CHANGE_NOTIFY request. Steve French and I had earlier a conversation about that. Before trying to make this work with cifs I've tried to make this work using a FUSE fs with libsmbclient. I did not get it working since the adding of an fd to the FUSE fs's eventloop was not easy, and required a rewrite of libsmbclient. The writing of the FUSE fs was easy, since there are already some examples.
