Tried between nVidia-nouveau desktop and headless server (glxgears at
headless server) and it works, if you can call it working.

Ah! That's interesting.
That's the closest so far to a reasonable test.

What I'd like to know is if how well it talks to to X-servers
on other platforms or if the X-platform was just split into
incompatible dialects?

It seems to be doing the rasterization in software on the X server, in
spite of having more than enough acceleration capabilities, resulting in
8fps or less (couldn't accurately measure).

Well, that's expected for Nouveau, accel is not complete.
Is none of enabled? Remote OpenGLX, by definition, did the rendering
on the client -- not on the server and sent down as a bitmapped image.

I used to get 30FPS running remotely with OpenGL on a 1Gb ethernet on
GLXGears (at it's default smallish window size).

If it is doing SWrast on the server and sending X frames --
then my initial assertion stands -- OpenGL **wasn't** rasterized and
sent to the client for display -- it sent the more compact
instructions to do transforms on the existing image. I.e. it was
more like SVG vs. PNG. With SVG a <100K pic can easily blow up to
several to scores of megabytes. The ratios get worse if SVGz is used.

I'm convinced that a swrast may be doing a bitmapped ship of the image,
I can easily believe that. But That's not OpenGL.

Nvidia's driver may be closed source, but the OpenGL standard
it follows is not. It has well published interfaces (wikipedia
has a good article on it showing the different revs.)
