FreeNX is the free implementation of NoMachine's NX X11 Proxy system.
Have not used Real NX, but on SUSE 10.x FreeNX is easy to install
(Yast add package and run 1 command)

Not Sure. Windows client from NoMachine does not seem have that
option, while the CLI nxdesktop on linux does.

Readonly would infer that you are connecting to existing session. Not
sure about this one.

glxgears in NX seems to work. Linux client gets ~200fps. A little
choppy, but works. Native on linux client ~2900fps. On server I get
~1700. Windows client is about the same as Linux client. It is CPU
intensive, as the session is not a simple redirect of local screen. I
am not a big OpenGL user, so I have not tweaked or tuned for max

Yep, by design it is SSH.

Personal preference. Compression is adjustable to maximixe B/W available.

The NoMachine web companion seems to enable this, have not tested
personally yet. Fairly lengthy install (Must install/configure
HTTPD), as it does not run an embedded HTTP like VNC (sometimes) does.

Would say yes. Still depends on RAM and CPU, but the commercial
version has clustering and load balancing (Like Citrix)

Not sure. More details needed.

I do know that the server needn't have xdm or a GUI running for NX to work.

Hope that helps.
