Don't we have the Linux case covered for like 99% with Xspice? All that is required
is for the VM and the guests to have some way to do a socket connection between the
2 (iow they cannot be on completely isolated networks).
You don't even need to do it in a VM then.

As for the windows case, I agree we don't have a solution for that and won't likely
have it in the future either. The windows case sounds to me like you just want windows
terminal server. You likely would need a license for that anyways even if you were to
use spice as the display protocol, because of how windows licensing works.
