Hi Rob,

AFAIK, mirrored baking should work perfectly with a mirror modifier. I 
just did a quick test and everything looked as I would expect, but maybe 
I am misunderstanding what you mean.
Could you post a picture and a .blend so that I can reproduce the error 

Also, what kind of normal map are you baking (Tangent Space/Object 
Space) & which render are you using to bake the normal maps with?

One side is as expected and the other side is completely the opposite. When attempting to make photo-realistic skin pores on an animated character, in which as much uv space as possible needs to be allocated to the face, having a mirrored normal only enhances the level of detail that can be achieved, while having to map the entire surface to have the normals right is a real obstacle for that goal.

Not only this but I would also be losing detail in having to share space with the other half of the model.
