Don't put too high hopes into it. I guess it would work great and easy 
if backside illumination also included specular highlights, but it 
deliberately doesn't.

You might get acceptable results with this approach though by moving the 
interior light source a deal towards the camera.

As for beta.33, double_illuminate will likely do the same trick; the 
major difference is that it ignores radiosity and photons (which may 
actually be of benefit in this case), and that you cannot control the 
intensity of front- vs. backside-illumination, but in this case you can 
achieve the same by tweaking the light source intensity.

To control the falloff of the light spot, you can tweak various parameters:

- The light source's offset from the center (zero offset won't do)
- The light source's distance-based falloff
- The brilliance parameter


Yet another, completely different approach would be to use light groups, 
placing each bulb in its own light group together with a light source 
straight in front of it, to generate a classic highlight.
