I run the Kstars, EKOS and PHD2 in the Pi. I use my laptop only to connect over VNC to manage the session. Practically my laptop is just like a remote monitor.
In your setup, every guide camera frame has to be sent over the network to your laptop. Then a guide decision has to be made in your laptop and sent back over the network. I would assume that this might create a lag or put pressure on your network. Also, why rely on two compute devices when one can do the job. Unless of course you are running indi on a very low powered rpi. I personally would like to reduce the number of points of failure for a productive session.
