FWIW, we built an incredibly easy single click OpenVPN setup tool for DigitalOcean and Rackspace during Sochi: http://www.tinfoilsecurity.com/vpn
Enter API key creds, it makes the box for you, sets it up, and hands you a config you can use for your client of choice. (The script is open source for those of you that don't want to enter creds - we don't store them, and actually remove access whenever we can; for example, we delete our own SSH key from DO because they let us).
It's still OpenVPN but might be useful to those that care about this story too.
This is such a nice product, I'm thinking you should be charging for it! I can't quite so who the market would be though. I guess there's not an easy way to target it to the enterprise market.
I've been thinking of how to market this but the only step missing is setting up the client. Bear in mind that this should be fool proof (typed up the instructions for a friend and still ended up with 8-10 steps). Tunnelblick for OSX is straightforward to setup with the provided .ovpn file but takes too many steps.
Thanks for the kind words - our main business is website security testing (check out our homepage at https://www.tinfoilsecurity.com) and we built this mostly for our customers to use to keep themselves safe. :)
