Maybe I'm missing something here, but the subport idea just sounds to me
like something that should be implemented in a device that maps ports to IPC
endpoints.  As I presume this is not going to be a common use-case, this
choice would keep the libzmq core simpler and move the complexity out into
an optional device.
