Abstract
A system and method communicates commands from a command originator to receiving devices, yet the receiving devices do not confirm receipt of the command. The most current command (e.g. the one with the highest sequence number) is rebroadcast by the command originator and the receiving devices, tending to be more frequent upon detection of an event indicating that the most current command was not received by at least one other device, and less frequently upon detection of an event indicating that the most current command was provided with sufficient duplication that if another device could receive it, the device likely did receive it, subject to a maximum and minimum rate.
