Conversely, technical solutions which do not take into account operational
reality don't benefit those who need them the most.

Sadly, we don't have the luxury of starting from a clean slate.


You started with a long list of requirements which had to be met by
interception. Now it turns out that the requirements on solutions came from
organizational issues you never told us about.

I still don't see a response to how you determine unauthorized access
happened without being the authority on what access is authorized.
Apparently exporting the PMS from clients and servers  isn't possible: I
find that hard to believe.

Let's standardize an extension that exports an encrypted EMS and be done
with this debate.
