Or xpra ("screen for X"), or NX, in which case you don't need to run
full screen.

For games and such you can use VirtualGL (works for both VNC and xpra),
hardware video decoding will still be missing, but for everything else I
don't think you will ever notice the difference in rendering
performance: the network/local pixel forwarding and client rendering is
much more costly than that.
