For the same size of network/organization with the same systems in
place and the same number of external partners who have org A's
addresses embedded in configuration on devices controlled by
Orgs. B, C, D..., the problem space is identical and the solutions
are also identical.  Given an identical problem with an identical
solution, generally, the implementation difficulty can be quantified
as also being identical.

Cost is only one form of pain.
