I usually don't set it up like this, but would the ShrinkWrap's Reverse
option do what you want? Nonetheless, one always has to be careful to
make the deformers behave to keep the Shrinkwrap in close bounds...

Shrinkwrap has always been a royal pain for me because of the way it
always snaps the deformed geometry onto the deformer. What you really
need is something that only deforms when the deformer pushes against
and through the surface. I’ve a couple of ideas on how to do it but
not really wrapped it up into anything firm. Anyone think there’s a
genuine need?

I think I like your approach better as it's more rigging-centric than
sim-centric. I did a quick test using your method and it does indeed
work well. I never thought to use shrinkwrap with weightmapped
clusters to localize the effect. Yeah, I prefer XSI for character work
over Maya. Betty kool.
Thanks very much for sharing. Heh, so simple and effective.

In very short, pieces of geometry placed under the skin with
deformations linked to the underlying bones and weight-mapped point
clusters on the character surface shrink-wrapped as Secondary Animation
onto the muscle geometry can get you pretty far. Certainly not a
one-click solution, though. Overall we have a very robust system of
deformation and animation mechanics in XSI which can be used in a great
variety of ways to achieve tasks in this field. It all depends on the job.
