Mike,
Are you asking if it possible to connect this device to an NXT brick or are you asking if you can interface it to the CAN buss and use it for robot control?
Under the Team Update #1 issued last night, this appears to be an NXT sensor so you can use it for that.
As to interfacing to the CAN buss, that might be a more daunting task and the rules outlined by Eric above apply as well as other electrical rules for power and wiring size.
