As can be learned from Zope community experience, images are better
stored to a file system, and database handles only image properties
and location.

Any... Sorry, not any... A _good_ patient tracking system should be
able to keep images of patient before, in process, and after
treatment, his functional outcomes (how can he stand, sit, bend and so
on, specifically to his pathology), his x-rays, photos of surgeries,
specimen images and so on.

Could you give me examples of real harmful consequenses of the
security violation in patient data systems where Apache-SSL was not
enough? Maybe i underestimate the problem but i don't really
understand its value - maybe it is obvious benefit from bank system
cracking or so, but why attack patient data management system?

What are you talking about - perfomance through dial-up connection or
local intranet in 100 mbit network?

Sure, this depends mostly on a server perfomance.

Why not target such a system mostly for Intranet usage? Or dual? Some
functions are needed mostly inside the hospital network (like image
preparation and storage), and some also through dialup like patient
questionaire filling...

And also there is a possibility to use "dual" interfaces for internet
and intranet. As well as button "Text only version" we can see on many
pages.
