The thing about that form of glow is that it's a post-render effect... meaning it won't actually provide illumination to other parts of the scene, it only "fakes" the glow. So if you do that, you need to create an invisible "ambient light source" to fake out the illumination coming from that region.
That's also a "node" effect, by the way, so I'm presuming that what you mention works much the same way?
Pretty much. This is all done in post. In this case (and with such an extreme glow) the setup involves making sure that EVERYTHING doesn't glow, just the bits I want.
