Don't you hate it when you send an email and half a minute later you
find the answer by yourself?

So the solution is:

class Hello_impl: public virtual POA_hellomodule::Hello
{
public:
	virtual char* helloWorld (const char* greeting) throw (CORBA::SystemException);
};

class Hello2_impl: public virtual POA_hellomodule::Hello2,
		   public virtual Hello_impl
{
public:
	void foo () throw (CORBA::SystemException);
};


I forgot that if Hello_impl inherits POA_hellomodule::Hello only virtually
but you instancize(sp?) a Hello_impl, it will (of course) get a fully
working POA_hellomodule::Hello ancestor.

You are in a twisty maze of little install diskettes.
