Have just been thinking - yes you probably could but (correct me if Im wrong) that method would effectively make the N900 disk available on Windows and would require Windows software to work? ie You would need to code a Windows programme?

If you used rsync it would work on the N900 independantly - ie rsync would access the server/folder on the network (either a PC or a NAS) and then sync.

Im not sure which would be the easier (or if Im making sense!) its just that someone mentioned it would be quite easy to do not sure what method he was thinking of: http://talk.maemo.org/showpost.php?p=341086&postcount=2
