Thanks for the explanation.  Brett mentioned something like runpy vs 
import using different techniques.  Which is OK, I guess, but if the 
command line/runpy can do it, the importer could do it.  Just a matter 
of desire and coding.  Whether it is worth pursuing further depends on 
people's perceptions of "kookiness" vs. functional and performance 
considerations.
