Only optimism.

Sadly that is what my research has told me too. But I refuse to accept this
reality (as I rely on Spice for my test VMs).
I have heard that RedHat has now decided to also support KDE as well as Gnome,
so this move gives me hope that sanity can prevail.

I would expect VNC or RDP.
Sadly it seems few take the Linux desktop seriously and only see Linux useful
as a 'headless' server OS, and hence normally use terminal access (ssh).
A day or so ago I was at a IT meeting and overheard a professional dismiss the
Linux desktop scoffing, "there is only Windows an MAC, no one [seriously] uses
Linux as a desktop OS". Those he was talking to all seemed to agree.
But if anyone was truly using Linux for remote "Virtual Desktops", I would not
expect they would not be using Spice but some proprietary remote desktop
software. If there is a company or organisation out there that is using Spice
for virtual linux desktops (say for 100 or more users), please tell me who and
more details about the setup.
Please note: There is always an exception to every rule.
