No, it's really easy. The server is just a file for communication between the table and backglass. It just sits in the folder.
You call the objects on the backglass from the vp script like you would vp lights.
Light1.state=1 is the same as Controller.b2ssetdata 1,1
1 (first 1) is the light ID, and 1 (second 1) is the lightstate.
Blinking (lightstate2) is not supported, but there's a built in animation feature for this purpose, although I prefer to manually script it in vp.
This is the best I could do with Little Joe I'm afraid.
