With a card you're able to do semi-transparency with the glass shader, but with a disc, which allows spherical projections, you can't. Why is this? Can the ability be added to discs?

The disc is rendered with the micropolygon rasterizer which has some differences from the ray tracer. You should be able to do spherical projection on a card simply by changing the texture space to world space with a transform shader.
