this was one of the 1st things that BMWG talked about when the WG
ws formed just because a lot of people would like to have such
a number - it is too bad that it may not be possible to come up
with one that gives the buyer any actual information to decide between
vendors on

that is about what I used to do (modulo alternating protocols 
within a packet size, I ran all the sizes then changed protocols but
I do not see any reason to do it one way or another)

but I do not see how that gets one closer to a single magic number
(which the BMWG designated a "millstone" after Dave Mills)
