  We introduce two processes where the BMS equation appears in a context quite
different from the original context of non-global jet observables. We note the
strong similarities of the BMS equation to the BK and FKPP equations and argue
that these, essentially identical equations, can be viewed either in terms of
the probability, or amplitude, of something not happening or in terms of the
nonlinear terms setting unitarity limits. Mostly analytic solutions are given
for (i) the probability that no $c\bar{c}$ pairs be produced in a jet decay and
(ii) the probability that no-$c\bar{c}$ pairs be produced in a high energy
dipole nucleus scattering. Both these processes obey BMS equations, albeit with
very different kernels.
