Lightburn on multiple PCs

I’ve been using the demo version and am looking to purchase a full license, but within the family there are 3 PCs and a laptop we’d like to use LB to design on and have mini PC in the workshop that would be used for local laser control, connection and possibly correction of files prior to burning and act as the server for the laser.
What do you suggest the licensing route to go? Potentially a lot of licenses!
Thanks
