As you probably read from the Khronos front page, the OpenKODE 1.0 specification is now final, and Acrodea has released free implementations for Windows and OS X (10.5.x, Intel processor), with Linux version on its way soon.

The libraries can be downloaded from http://www.acrodea.co.jp/en/openkode. The package also includes OpenGL ES 1.x and (experimental) 2.0 implementations over desktop 3D hardware.
