Well, I've got news for you: POV-Ray has been able to use arbitrary
coordinate systems for ages ;)

For instance, to get a right-handed coordinate system with Z up, simply
specify:

    camera {
        sky       z
        up        z
        right     x*ASPECT_RATIO
        direction y
        ...
    }

and Bob's a relative of yours.

The slowdown upon both export from Blender and import into POV-Ray
should be negligible, and the slowdown during render is non-existent.
