Hi All,
I've recently released code and instructions on GitHub on how to build a Domain-Specific VPN router based on a Raspberry Pi.
This solution allows for a plug-n-play appliance that you install between your provider modem and your router that allows for multiple outbound VPN connections (PPTP only for now), for each VPN connection you can specify a wildcard domain to route down it. This way "normal" internet connectivity remains on your native connection, but domains you specify as "interesting" route down the VPN connection you specify.
Hope this is of use to someone.
