Indeed it is possible to run/display NVIZ remotely.  You need the 
MesaGL software rendering libraries on the machine on which NVIZ 
is run.  The MesaGL software renderer takes OpenGL calls, and 
turns them into "straight" X calls.  I do this at home once in a 
while.  You may need to perform LD_PRELOAD hackery with a 
symbolically linked libGL.so -> libMesaGL.so in order to bypass 
the system OpenGL libraries (which may be optimized for direct 
rendering, or implemented via the GLX extension to X).
