Some comments on the original design of MailMan's server and patient addressability capability

At today's architecture call, folks talked about the Extended Action Protocols of VistA.  This reminded me of some of my original design goals for MailMan, which I thought I'd comment on here.  I don't know how this all relates to today's VistA platform, but here are my thoughts from days of yore...

Why we need to move away from the "Castle-and-drawbridge" architectural model.

On today's architecture call, someone mentioned that the North Chicago site had three different security domains - one each for DoD, VA, and Navy, requiring separate logons, and who-knows-whatever-else to make it work.  They have encoded three different "castles" within the system, each with its own "drawbridge" between it and the others.

This kind of design doesn't lead to triple the complexity, but rather it squares or cubes it with the number of sites involved.
