You could try a shader that does edge detection and above a certain threshold apply a simple blur. That should give some sort of AA. A more complex version could adjust the blur based on how strong the edge is.

I know, this is not a specific GEM problem. I would like to get the render (started with only geos) from the [gemframebuffer] anti-aliased. And I was wondering if someone has worked on a shader to get this effect and if this person would like to share his shader or to help in development ?
