Two phase commit, for example to guarantee once and only once message delivery in MQTT. I like how far you can get with such a simple protocol:
A to B: send message (repeat until ack)
B to A: ack (resend if a repeat of message is received)
A to B: commit message (repeat until commit ack)
B to A: commit ack (resend if a repeat is received, but commit only once)
