I'm so curious about what the 30% of you who are designing custom UDP-based protocols are doing, I would love to hear more!

(please only reply if you responded “yes, UDP” to the above poll)

@b0rk The ability of UDP to broadcast to all computers on a local network is handy. As part of a GUI for an industrial robot, I wrote a simple UDP protocol to discover all robots on the local network. The GUI would use this information to allow connecting quickly to the robot without typing its IP address.
