And that's my point.  In fact, that's always been the point.  Let a machine
do whatever it is the machine is best at.  The 400 is best at database
processing.  The workstation is best at UI.  Let them each do what they are
best at.  Separate the layers of your application so that each can be
deployed where the best fit is.  This is why I think interconnectivity is
the key to future application design.

You know, both the AS/400 and the workstation are already n-tier machines.
The AS/400 has a multitude of subprocessors (which is the reason it runs
rings around other servers).  But even your workstation uses a distributed
architecture.  Your graphics card has an onboard chip is basically another
CPU.  Your network card has a processor, so does your SCSI interface.

The idea of using each machine to its best potential is hardly new, and the
trend is increasing.  I may be totally offbase here, but I am willing to
wager that there will be a higher rather than lower percentage of 400's
being used as pure server machines (as opposed to all-in-one processors) as
time goes on, and this, in my mind, is the best use of the machine.
