WebUI pages needs to know the LJ IP address.

The server approach is based on redis, so you can write and run your laser client software in any redis capable programming langage (50+ : https://redis.io/clients). An external program that just send pointlists is a "client". If you want some interactions from the webUI, like text status area support, crash detection, launch,... it's a "plugin" and some default code is needed. See custom1.py, a basic plugin you can modiffy. LJ and plugins signaling is mainly over OSC.

For nice lines and angles all user pointlists are automatically resampled by tracers. There is 2 cases defined for resampling strategy : short and long distance between 2 points.
