One nice thing is that when you update/change/switch distros, etc.,
you can run old/new in parallel.  Another is that you can easily move
the VM elsewhere if resources are available and it is mostly
transparent to your use as a desktop.

Freenx/NX does all the same things as native remote X, but with better
remote performance and the ability to disconnect and reconnect  (even
from a different display) with everything still running.   There is
probably some memory overhead for the proxy/cache buffers, though.
