Luis's assessment sounds about right to me. SpatialFunctions are a good 
starting point but they aren't (and aren't intended to be) a robust 
description of global shape.
A few other thoughts...
At the NLM meeting, Luis and I talked about extending 
InteriorExteriorSpatialFunctions to include boolean operators; for example, 
syntax for a hollow sphere might look like:
itk::InteriorExteriorSpatialFunction hollow = exterior&&(!interior);
This is a post-beta task. There was also discussion, some months ago, about 
representing masks as InteriorExteriorSpatialFunctions as well (with 
ConditionalIterators as a means of navigating mask-space). If there is 
going to be more interest in this sort of thing, it probably merits further 
discussion.
