On the surface, this seems like a great idea and something I've always wanted to play with, but I'm a little confused as to who is the target customer?<p>For the average consumer who wants a VPN, it's risky to only use a hardware device (transparent VPN) since there is no protection against IP leaks caused by the OS or something else messing with the routing tables. Maybe as a network-based last layer of defense, but not primary. I'm sure you've encountered Wi-Fi and Ethernet connections deprioritizing and causing routes to flip without the user's knowledge. How do you deal with this?<p>For businesses who want to a secure PnP solution to connect multiple sites together with a transport protected by hardware keys, sounds like a great solution. No need to shell out for bulky hardware VPN gear.
