Update external service

[saulshanabrook]

Have you thought about allowing apparatus to talk to external services?

For example, I am doing some work with stage lights. It would be really cool to create things like that RGB slider and have that control a physical light. To do this however, it would need to send some network traffic on every update.

For example, you could add the ability to send a websocket message on every update of a certain variable...

Or maybe it makes more sense to have the other outputs be represented physically on the screen by something.
