Interestingly this doesn't quite work, but I used the principle.

The Kernel module is mixed into Object so when you use `shellcommand... 
` you can intercept the call on the object itself.

So I was able to:

@my_obj.stub!(:`)   ...in the before block


@my_obj.should_receive(:`, "wget...")   ...in the test

and use the short form:

`wget... `   ...in the actual method.

Thanks for your help chaps.
