I'm running a Makerbot 2x I just tried it with a Gcode that uses the Dual Extruder and it works also. I want my buddy with the Ultimaker to also try it, and see how we can share the printers online just for fun. Personally I don't care about the security, but the remote control web camera feature is really useful. Going to chat up the support guys and see what else this thing can do.
