Hi Magnus! Old colleague from Nationaltheatret here.
I guess you already had your show, and found a solution by now.
But i've written a simple Node.Js Server to achieve what you want.
you'll Need the hub, but that could be connected with WIFI or Ethernet near or on the stage.
Then my script receives the HTTP request from the hub to the show computer running the server, and sends OSC messages to QLab.
I have made an Alpha version of this, and i will upload it on my github tomorrow.
Håper det står bra til!
