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)

(Didn't design it, did an independent implementation and a lot of packet level debugging - and I didn't see any other multicast examples) LCM is a multicast messaging system used in high speed robotics - it's UDP primarily because it is multicast; it has different message types for longer multipacket messages.
