It would be nice if you could use alpha channels for transparency, and
then layer multiple shaders on the same surfaces... ala Alias.
Seriously... now that 4.0 Final has made strides with IK (good job!), I
see LW's texture capabilities as its weakest link.  It would also be nice
to be able to keyframe texture parameters.  Also, are we gonna see any
more of the Essence shaders ported?
