Hi ..could you give an example what that would look like ?
Are you referring to the effect based on Starwars and other movies ?
Maybe you have some pictures as example ?

Thanks for the example.
Looks like it's a tinted rendering mixed with an alpha (incidence based) and some outlines mixed.
Also the plate behind it becomes a bit blurred where you look through the transparent part.

You can do a render of your element, another layer for the alpha based on the angle and some outline shader ..

Or render all at once if you want.
Then have nuke to adjust the plate behind the rendering ..you could even do that in clarisse if you like.

I can setup a small example tonight...

This should be pretty easy to be honest, I can think of a few ways I'll work something up as well. Raytraced curvature, facing angle tools, multiple layers composited one with a slight blur, screened on top of base render..etc.

Multiple ways to skin this cat, as they say!

Update, ok I worked up a super quick proof of concept. this is the first way I'd do it. Just a simple emitter shader, then using the outline shader and some compositing. I will try to work up a more complex version, I'd like to do a "hologram" but would look more like Tron 2.0, with an outline around distorted glass. Would look super cool. But this example should get you started!
