Hi,

Yes.

Currently yes, althrough the plan is to support gl display remotely in
spice. The workflow will be completely different though. Non-gl spice
uses the classic display channel, the plan for gl spice is to feed the
dma-bufs into the gpu's video encoder then send a video stream.

Yes. Any qemu display device works with gl-enabled UI.
cheers,
