I released a packaging of some DJB tools and some custom code to give you Rendezvous email, a local DNS cache to futher speed name translations, a POP server, and a secure, simple, local SMTP server that you can use everywhere instead of switching everytime you change your network environment. You can find it here: http://au.gu.st.

As this is an alpha, I'm looking for feedback, mainly in how the UI should behave. Perhaps moving the whole thing to a preference pane. Also looking for general usability comments on sending email via Rendezvous. Pick a name and append "@gu.st" to email me.
