The zero-length payload size shouldn't be an issue, but UDP doesn't make any guarantees about delivering the message. Your UDP application must be prepared for some, most or all of the messages disappearing without any error indication. In practice, you'd end up implementing your own TCP on top of UDP (retries, timeouts, acknowledgements, sequence numbers etc). Marko -- https://mail.python.org/mailman/listinfo/python-list
