Well, I'd like the goldwater API to be available from within the pnet VM in 
the DGEE but nowhere else.  Internalcall seems to lend itself to this.

However, if the webservice requiring access to the goldwater api was written 
in python then it would be using a SWIG'd mechanism.

So I might be better off SWIGing everything I need up front.
Food for thought.
