Detecting where an object is touched

i'm pretty sure I'm pushing my luck with this one...

Is there anyway to detect on a *single prim* the exact x,y,z coordinates where a touch occurred?

Say I have a cube 1x1x1 and I'm facing its frontward pointing face. If I click on the nearest topleft corner could I return something like -0.5, -0.5, 0.5? Or if I click on the nearest bottomleft corner can I return 0.5, -0.5, 0.5? Or touch it dead center of the closest face and return 0.0, 0.0, 0.5?

No there isn't currently.

It would be good if you could tho, even if it was just seperate for each face, it would be a good start. Or imagemaps would be even better.

There's no reason why we can't be passed this information. The Havok pick is cast from the user into the world, and the x,y,z point it intersected an object IS returned to the source code. They just need to add an accessor function to LSL.
