I call BS, I would really like to see someone prove that these are all really raspi units and not just Debian Squeeze instances running on a virtual server.
Also, I have a raspi myself. The beauty of the raspi is not that you get to eat the pie, its that you get to make it yourself. Cloud connected? I think you mean Internet, not cloud. You know, unless these are Debian Squeezes on a virtualized box. Don't have the time? Then you can't have this hobby. End of rant.
