Agreed, and i think an important in cloud-like infrastructure environments.

Lucy, do you know if RDMA supports SSL or something equivalent?

Alternatively, we could look at slotting it in as a new protocol family implementation along the lines of the DatagramChannel.open(ProtocolFamily) method.

Peeling the open methods and consolidating into a separate specific RDMA class or classes is i think better than spreading around the existing nio classes.

It’s hard to provide more concrete guidance without a webrev, looking forward to that.
