Have you considered using of SCTP for minion master communication ?

Over the years we have considered many different transport systems fro Salt. Due to the fact that the transport in Salt is built on top of ZeroMQ it has repeatedly proven difficult to replace it in a reliable way. This is one of the motivators around building POP, as I look back at Salt my biggest regret was that it was not MORE pluggable. I have often wanted to be able to more easily add new transports. I think that a Salt Transport based on SCTP would be an excellent idea. But given how difficult it is to add and maintain transports in Salt I am hesitant to change, especially since the ZeroMQ transport works quite well at this point.
