Hey! That’s awesome, thanks for trying out the program!
The Relay plugin option is so a relay sends positions to Kantab instead of Kantab taking the mouse’s position, so relays would be able to make use of more information they could get such as pen tilt and pressure
Right now the only relay that exists is a browser extension I’m developing and it’s currently unfinished, so sadly there’s no real relays out there (Not many people talk about Kantab :( )
However, what you describe as your use case is VERY interesting and the way KT works is by exposing a webserver in the given port, so theoretically by being in the same network you could load up the URL by entering the tracked device’s local IP and the given port.
I’m interested in helping you with this setup! If you have a Discord, we can talk – send me a FRQ to the same username I have in itch (of course, all lowercase)
