	I too am rather interested in this; is the only way to marshal an array
of a structure to send an array of dicts - each containing a dict
containing a single member of a new type (with a single bogus named
field) containing the value ? ie.

	struct Foo {
		int a;
		double b;
		string c;
	};

	typedef sequence<Foo> Baa;

	->

	array<Dict<Dict>>

	Where we might have:

	array[
		Dict<Dict> (
			"a" -> Dict<int> ( "" -> <valueof a> )
			"b" -> Dict<double> ( "" -> <valueof b> )
			"c" -> Dict<string> ( "" -> <valueof c> )
		)
		...
	];

	[ of course - this being highly notationally confused ;-].

	Of course - if you're not writing something extremely simple - perhaps
you should consider using a more meaty IPC system such as DCE, DCOM,
CORBA or somesuch ?

	Regards,
