Acknowledge received message

By replying back. I want to ensure the status was changed successfully. Could be useful to also include in the reply whether the sent command was valid.

UDP is not reliable. You can wait for infinite amount of time for your ack.
Is it ok? What use case do you need this for?

I guess I could just time out after x seconds.

It's normal to want to know if an operation succeeded. Imagine I use AnyBar to indicate whether the test suite passed. I would want to know if the status dot isn't correctly updating.

How about a anybar command that returns the current state

anybar red
anybar status

Outputs "red".
