     Nope. You have to eliminate all shading from the scene and re-render
the animation (pretty quickly, thank goodness) to use the resulting frames
as a mask. I've done it often and, while not terribly convienent, isn't
that bad if automated. Alpha channel support is high on my list of Imagine
upgrades if someone is still compiling a list. 
     I will say, however, that the surfacing tools for Imagine are
EXCELLENT for the hobbiest (of which I am not). Forge and Essence,
combined with Imagine seems to be impressing even the SGI people I know.
Too bad about the interface (Imagine, not Forge ;-).
