I have posted link on HN to Dataforge UUCP because I have been interested in store-and-forward networks for a long years. All my email passing between notebook and my email servers used UUCP-over-SSH for years. But soon I create NNCP (http://www.nncpgo.org/) project and totally moved all my email/files store-and-forward networks to it. Possibly it could be interested to you.
