It's an input parser per twiddler object, but yeah, I thought about that.

It seems an awful lot of extraneous code though :-/
(I have to register factories for utilities even where the utility is a 
simple python function, and I need several new interfaces: 
IInputFactory, IOutputFactory, IExecutorFactory,IFilterFactory)

I dunno, I think Lennart is "right" here, but that "factory" attribute 
to the utility directive is hard to ignore...

cheers,

Chris
