id Software Lead Programmer John Carmack updated his .plan with his ideas on what would help progress in development of OpenGL drivers and applications: an "Independant OpenGL conformance nazi." Here's a bit of the much larger update that goes into detail about this concept:

I think there is a strong need for a proactive, vendor-neutral OpenGL watchdog, or even a small group, especially in the linux space.

I have been working on the utah-GLX team for quite a while now, and while I have been very pleased with the results, I would like to see more effort spent on doing things as right as possible. Because the developers (me included) are basically just doing the work in their spare time, testing usually only consists of running their favorite OpenGL application, and a few of the mesa demos, or some of the xscreensaver hacks.

Recently I did the initial bringup of a RagePro driver on linux, and I was much more conscious of the large untested feature space, and the tunnel vision I was using to get it to the point of running Q3.
