Are you sure you don't want VirtualGL instead?

There is no official GLX protocol for OpenGL 1.5+. NVIDIA implemented
unofficial protocol with their AllowUnofficialGLXProtocol /
__GL_ALLOW_UNOFFICIAL_PROTOCOL settings.  I think it allows up to the
OpenGL 2.x range but I haven't looked in detail.

There was a company out of the UK that supported this protocol in their
server, IIRC, but I forget their name.

Mostly people don't care about that support because by the time you're
using those features your app likely cannot stand the performance hit
from indirect rendering, so a form of server-side rendering is used
instead.  See VirtualGL.

HTH,
