I recommend use multimaster fkie for multiple PC. In my experience, it's a much more convenient way of dealing with multiple machines compared to the traditional master-slave setup. This isolates each machine, and makes implementation/debugging/scaling much easier. Using the multimaster_fkie framework, you would bring up a roscore on each machine, and run the multimaster fkie sync node to sync desired topics over to your machine. The desired topics can be specified using rosparam. This setup also makes RVIZ visualization on your PC much easier.
