For http://Clara.io, we explored a bunch of headless gl solutions and none worked. It may have changed by now. But even if you got a headless gl solution working, it likely would have poor extension support, which means the results will suffer anyhow. :(

So did you take any other solution? I was thinking about renting or collocating server with gpu and just automate whole process with ansible/fabric or just vnc. About exentions - thats true. I was able to run software rending for shaders (llvm, xvfb, ec2), framerate was acceptable (1-5 fps, which is more than fine for screenshots), but issues like having max anisotropy = 1 make it unusable for this use case.
