If you have a dedicated Wifi router on your show computer with no other access "permissions", wouldn't that be "secure" enough for this purpose? I would also think there would be some sort of security key (similar to the way satellite receivers work) that would allow the app to only schedule the requested event with no other abilities to access the show computer. I'm not well-versed enough with networks or software to know how something like this would work.
I would foresee using this as a "make your own sequence" where during a specific song during the show, kids (and their parents) would be able to spin the mega tree, tap to light the window frames, change the colors of smart nodes, light up the roof, etc. Obviously, there's no way to configure for everyone's individual layout. Maybe also allow each item to be logged into one at a time.... for instance only one person can spin the megatree at a time.
I love the potential this has!
Matt,
This sounds awesome! I, like many others, wouldn't have had a show this year had it not been for xLights! Keep up the great work!
