That's interesting Jim,
Now what do you mean by " emulate that with a rendermap"? Is there some
kind of workaround? Any explanation of the workflow would be really
appreciated.

Yes, it's possible. I believe that the mental ray fast skin shader uses
a similar technique. The first pass of the algorithm requires a
lightmap shader, so in XSI you would have to emulate that with a
rendermap.
