I'm implementing the "[RFC virtio-dev] vhost-user-slave: add vhost-user slave device type" device in QEMU and DPDK in order to show how the ideas we've discussed work. Here is the VIRTIO spec link again: https://stefanha.github.io/virtio/vhost-user-slave.html#x1-2830007 It integrates into DPDK's librte_vhost so that existing vhost-user code works over AF_UNIX and virtio-vhost-user without code duplication or rewriting the devices. I hope you'll like the code when it's done. If not, it still has useful code and ideas that would be needed to complete the vhost-pci RFC work like extending the PCI transport in the VIRTIO spec, handling vhost-user reconnection, etc. I'm aiming to send an RFC in the next 2 weeks.
