What I would like to see is a virtual video driver for the Linux kernel in order to implement SPICE support on real hardware. (SPICE depends on virtualized hardware to provide it's connects)
Then I would also like to see a WAN profile for SPICE. Currently it seems to only be really good for LAN connections.
That way instead of just having your GUI work over the network you have _everything_ work over the network. Virtual consoles, framebuffers, and anything else. Any sort of video output post-initrd would be able to be sent over the network.

But making this usable for unprivileged users would be... tricky.

Yes. You would have to treat it like a multihead workstation were you have a video card dedicated for each user.

Surely userspace can just send the command buffers over the network rather than to the DRM driver?
Don't see much point in using a kernel driver.

Nope. Command buffers are too huge for that.

Why is Spice hard to implement in Wayland? Isn't it just a protocol?
Or is Wayland the problem rather than Spice?

Spice is not particularly hard to implement for Wayland. But nobody got around to doing this.

Oh, is that what XSpice does? It's hard to tell: the page you link to never actually says what it is. Actually I'm still not sure. Is it an X video driver that sends the image over a spice connection to a remote client? (If so, that's not going to work for anything but X.)

Basically it seems to be a 'virtual GPU' (driver) for X.org:

But the same principle obviously can be applied to Wayland...?

Oh, hang on, it's just another name for x86-video-qxl. Of course. *slaps self*
NX for Wayland? Posted Apr 13, 2012 14:08 UTC (Fri) by nix (subscriber, #2304) [Link]
That would be xf86-video-qxl and my fingers are dropping keys and LWN needs an edit option and a pony.
