Yup - found that one, but that's still 2nd hand information and not
supported by measurements. I asked him directly about it to see if he
tested this with traffic.
I still remain open to the idea that this may work, but I'd like to
see it. I don't have measurement equipment required to test this in
detail.
I wonder if we could test this with a simple ping?
