I said "they have the freedom to use any protocol they wish, even SCTP, as
long as
the protocol provides reliable delivery."  I also said "does the other
protocol obeys the fairness rule of Internet?  I assume it would."  I don't
believe UDP fits these two statements. However, talking to a device of its
own kind does give it the freedom in choosing a protocol.  I did not say
that it has a blank check to do everything.
