If I understand you correctly you're asking about environment mapping.

If so then you can get this kind of effect by using a sphere (or cube)
with the no_image and no_shadow tags surrounding your reflective object.
This means that it only shows up in reflections, so is visible reflected
from your object, but is not rendered otherwise.

Obviously this will begin to fail if your object is visible in a mirror
anywhere - the surrounding mapped sphere will show up instead.
