Ok - I eventually solved my own problem.  For any who may experience the
same thing here is the solution:

If you wish to use a TRemotable descendant as an output (reference)
parameter from a SOAP server (mine is an ISAPI) in Builder, you must make
the parameter type a reference to a pointer.  Nothing else will work.  A
pointer will not work (unlike returned objects which do work through a
pointer), a reference alone will not work (the Builder WSDL publisher turns
it into a const *).

The solution is to use: *&

EG:
virtual TReturnedTestObject * GetTest(TTestObject *& ATestObject) = 0;

Viola.
