I don’t know how long this will stay up, but I’ve been playing with my new Raspberry Pi and have a live ContentBox site running on it using the CommandBox embedded server. You can see it here
The unit is just sitting on my desk at home, so if the link’s down it probably just means it got unplugged or I took it downstairs to play some Minecraft Pi on the TV 
Thanks!
