An interesting travel router which ships with OpenWRT. Appears to be able to bridge wifi networks to tunnel traffic through a VPN.

Extremely small, the interface on the admin panel seems easy to use and connecting it to a wireless network was pretty easy. VPN configuration was painfree. Now I just need to actually travel somewhere to try it on public wifi.
