[dnssec-deployment] binary arthimatic

Can't say if I really agree with it or not, but considering most .gov
policies go with "use a minimum of X bits", the NIST DNS Security guide will
state something along the lines of choice a) (smallest key).

I don't know if that is sufficient, but it should be.  Enough thought goes
into determining the minimum length (by people smarter than I), to put trust
in it.
