I am working on an update of the previous WL memo,
but it is not going to be very much different.
The requirements are unchanged and are not compatible
with the strawman ops plan (not enough R exposures per
patch over 10 years).  

Part of this delay is that I was waiting for calculations
by Lloyd Knox and by Wayne Hu, which I now have.  I want
to run this all past our WL group first however.  I am on
travel until the 21st so this may have to suffice for a
few days.
