2017-05-18 03:39:47 -0500 marked best answer Is it possible to run ROS Indigo and Kinetic Kame on multiple machines together?

Hi, I have a PC (Ubuntu 14) and nVidia Jetson TX1 (Ubuntu 16) and I know that Ubuntu 14 can run ROS Indigo and the Ubuntu 16 can run ROS Kinetic Kame. Of course I can install Ubuntu 16 on the PC but I have some comparability problems with my applications on Ubuntu 16. So I want to run ROS Indigo and Kinetic Kame together in distributed mode. Is it possible to do that?
