I can see some good use cases for having a socket to do IPC between OS
images that have a shared memory interconnect. What I see as most
problematic is to have it defined in a way that is tightly connected
to specific hardware from one vendor. If the protocol was defined
in a way that is useful for communication between virtual machines
(e.g. on top of virtio) and tranparent PCI bridges, it would probably
be much more acceptable.
