there is nothing fundamental blocking AA in the XSI viewport. The
problem is that if it's forced enabled in the driver, XSI
[can't]/[doesn't know to] turn it off when it does its raycast selection
pass. Something implemented with display passes should not interfere
with selection; it's all ok as long as you clean up your OpenGL states.
Now the AA extensions actually requires buffer setup that needs to be
done by XSI when it's creating the view, so I don't think you can turn
it on at all from a shader.

Though we won't get antialiasing in the working viewport because of
the way selection
works right? It'd require a rewrite of all the selection tools I
imagine. Wouldn't DOF cause
the same problem?
Cheers,
