Hi Horst,
Yes, this is the stuff I was trying to get to, thin/thick client/server,
GUI's, application implementation approach, propriety/open/mixed
standards, etc.

We have taken a different approach. All our printers have network interfaces,
either built in or external print servers.
Our practice software runs on one server only - both Firebird SQL server
backend and GUI clients, and setups are *per room* - meaning the user logs
into a "room", and then logs into the practice software as "user". Computers
with known IP numbers log automatically into the correct room, but iof you
take for example a laptop you would simply plug into the hub in that room,
type "ssh -X <room>@<ourserver> <ourprogram> and it would launch the
graphical user interface forwarded to your laptop, and it would use the
printers configured for the <room> you logged into. The graphical user
interface prompts you for your personal user name and password then.
This means we can use our server either from thin or from fat clients, but in
any case, there is *nothing at all* to configure on the clients. We can use
*any* computer with network card running *any* operating system that can run
OpenSSH and X (is there any operating system that can't?) and it will always
do what is configured on the server.
The server has an external SATA hard disk RAID system (bootable) containing
evrything we need to run our practice network apart form the local print
servers per room - meaning if we get a hardware failure on the server, we
simply plug the SATA RAID box into any other machine with SATA port, boot,
and we are running again, without having to reinstall or reconfigure anything
at all.
Anybody can do that. Most people (including those who make a living from
installing practice systems) simply don't know that this can be done, and
those who know that it can be done rarely realize how *simple and cheap* it
actually can be done. Visitors are welcome to my practice to see it in action
and learn howto.
Horst
