@redstar64 Yes you can move the stick from house to house and TV to TV. The only slight annoyance is you will need to enter the new wifi network (from the Settings>Network section on the stick homescreen) when your son takes it to his dad's house, and then you will need to do the same when he brings it back home (the stick doesn't remember multiple wifi connections, so you'll need to enter the details each time).
Otherwise you'll be fine.
