glshim just got a new release (0.4) which basically allows you to recompile an (older) open-gl engine with opengl-es support.

Might also be adapted as a webgl wrapper (since I was told that is based on OGL-ES)?
Anyways, seems like a cool way to port a game to one of those ARM development boards that do not run a full OGL like the new Nvidia K1s
Might also help with an Android port?
Edit: there seems to be another project that targets webgl: https://github.com/p3/regal (and other stuff I guess)
