after setting LIBGL_ALWAYS_INDIRECT=1 glxinfo shows OpenGL version string: 1.5 Mesa 6.0 but doesnt show all extensions necessary for OpenGL 1.5
An application only checking for GL_VERSION 1.5 would probably fail.
Any idea what would happen with libGL.so / libGLcore.a from different versions of XFree86 / DRI and/or different vendors (nvidia) on the client/server machines?
That's *bad*. It is currently *impossible* to have GL 1.5 with indirect rendering because some of the GLX protocol (for ARB_occlusion_query & ARB_vertex_buffer_objects) was never completely defined. Looking back at it, we can't even advertise 1.3 or 1.4 with indirect rendering becuase the protocol for ARB_texture_compression isn't supported (on either end).
Please submit a bug for this on XFree86. Something should be done for this for the 4.4.0 release.

Does anyone know if either the ATI or Nvidia closed-source drivers support ARB_texture_compression for indirect rendering? If one of them does, that would give us a test bed for the client-side protocol support. When that support is added, we can change the library version to 1.4 (i.e., change from libGL.so.1.2 to libGL.so.1.4, with extra .1.2 and .1.3 symlinks).
