I was thinking back to the 1-Port router idea and now I am thinking of adding an OpenVPN to the mix. I could have an encryption key on both sides of the connection to give my setup a little extra protection.

I could have most of the ideas that I have come up with resident in this setup. In addition, I would still like to have a selection switch that would give me some different options, like TOR, w/wo OpenVPN, etc. The bubble chart would look like:
