  Hi,

> can we reach agreement on whether vsock should be involved in this?

I think the best approach would be to have guest proxy and host proxy
use vsock for the wayland protocol.  Use a wayland protocol extension to
reference the buffers in stdvga / ivshmem / virtio-gpu.  Only the two
proxies need to understand the extension, the client <=> guest proxy and
host proxy <=> server communication would be standard wayland protocol.

cheers,
  Gerd
