TOMEM  Peer to peer networking is ok for those who are happy with it, but this isn't what the internet was designed for. It would seem much more powerful and valuable to me if the notebooks were saved into a network viewable and editable format on a plain vanilla FTP or WebDAV site like .Mac. Sure that takes a machine that is continuously online, but otherwise notebook sharing has to be synchronous, which is not going to work very well.

For comparison, check out Projectforum.com, which has a simple but easy-to-use solution for a collaborative server.
