This feature is already in Open MPI for the last 6 months. Port
limitation was implemented for both the OOB TCP and the BTL TCP, with
and without ipv6 support. Setting the min and max to the same value,
force Open MPI (including ORTE) to use a static port.

I don't think this is the role of the runtime. Any user can write a 2
lines sh script to do this, there is no reason to integrate it deeply
