It would likely just be easiest to switch around the network configuration every time you move. It takes about thirty seconds.
RoadRunner uses a DHCP on their end, to give you an IP, so that's automatic. At work, you said you have a static IP, so you'd just have to enter that, and bring the device back up. You'd be set. Then again, I don't have any experience using multi devices without them being constant. James
