Hmm... along the lines of --multiply I'd have said --outer as in outer product. You could then also have --inner as in inner product which would concatenate lines from multiple files prior to processing. I'd think something called "--nest" would be handy for situations where one wants parallel to invoke parallel. - Rhys
