Cool! It's one of those things that would be nice if you have the
hardware. We regularly use clusters that have IB fabrics, though are
mostly dealing with lower message volumes and embarrassingly parallel
applications.

It would be especially great to see this sort of feature come through
to the language bindings and toolkits that leverage them, this would
be a pretty nice addition to IPython's parallel computing
capabilities, for example.

Though if this made it into ZMQ I might lose interest in ever properly
learning MPI. And on that topic, ZMQ provides the sort of
loosely-coupled messaging paradigm that is needed in HPC as parallel
applications deal with the realities of running on big systems (100s
of petaflops with >100k cores).

Good luck with it!
