We're in the process of reviewing the specification, the latest version (v7) is here: https://www.mail-archive.com/qemu-devel@nongnu.org/msg763207.html. We haven't had any reviews yet for that revision, IMO we're getting close.
FYI John Johnson is implementing the relevant changes in multiprocess QEMU. John Levon, Swapnil, and I are implementing the server part in libvfio-user (formerly known as MUSER). We also have a mailing list now: https://lists.nongnu.org/mailman/listinfo/libvfio-user-devel. We've been working on integrating the two parts.
Finally, Changpeng is implementing an NVMe controller in SPDK. We're trying to make it work with multiprocess QEMU and libvfio-user, we're very close.
