Cool. In your talk you even mentions multiseating.
AFAIU with this technique one doesn't get multiple /dev/dri/card* for
a GPU out of the box, so it is not possible to use unmodified
modesetting driver to run multiple X servers.

In DRM, only one application can be drmMaster at a time.
This is one of the reasons why one can't run a Xorg server per Connector to
have multiseat with one GPU.

shared-modesetting) which will offload mode setting to a helper dae
