One thing I haven't tried yet is to mimic SLI at the viewer level by creating two cameras and two contexts, one per card, then slit the up final window between the two windows i.e. top half, bottom half then manually composite the final result by copying the data from the second window to the first one.
You could probably set up osgViewer to do this via several slave cameras and custom camera post draw callback which does the copying from the second card to the first one. The copy would be real slow as it'd be read back to memory and write back to the first card, but for certain models it might be a useful gain such as volume rendering. Ideally you'd want this copy done over the SLI bridge, but without extensions to access it this won't be possible.
