​for remote visualization, you don't need a VMD plugin. rather you either
need an OpenGL capable remote desktop software and launch VMD​ then
remotely and used the matching remote desktop viewer locally, or run VMD
remotely and use X11 forwarding and GLX (embedding of OpenGL into X11_ to
redirect VMD's windows to your local machine. this latter option requires
compatible software and X11 and OpenGL configuration on both ends (not
common). the difference between these two methods is, that in the first
case the rendering would be done remotely using the remote desktop software
and then pass the rendered screen output to a "viewer" software in a way
somewhat similar to video streaming (it is still interactive, though). in
the second case, only the realization of the visualization is done
remotely, the rendering is don't local from the OpenGL instructions
embedded into the forwarded X11 display. there are benefits and
disadvantages for each variant.
