Sorry about the lack of updates, work has been hectic.
I have been looking for some “easy to setup” VPN systems for a while, especially since Hamachi is going from benevolent private to private-enterprise private. and I stumbled upon OpenVPN.
I’ve been floored at how easy it was to setup a windows workstation connecting to a linux server, routes and all, much easier than ipsec/*swan.
I’ll write up a guide on my wiki, as the “simple shared key setup” isn’t quite as copy/paste friendly as I’d like, I like to skip the whole RTFM section and get right into it, and I assume there are others like me.
