Nathan:

I do not have more than one Leopard yet.  I would be willling to buy a
second one if I saw the support for it.

As to the design, I know that the internal Leopard event code seems to
recognize a module number & button number combination.  I assume that module
number refers to multiple Leopards.  So, this would seem to support what we
want to do.  I don't see support in Mark's interface.  Also, I don't know if
this is supported through the serial interface at all.  Then, there is the
matter of screen switching.  I know this is done in internal Leopard code by
changing the value of Paramater #63.  I can't recall if there is support for
doing it on another unit.  Again, I don't know if this is supported through
the serial interface.

From an architectural point of view, it would seem simplest to treat the
entire network of leopards as one device.  Then instead of just sensing a
button press, you would sense a leopard number & button press combination.
Likewise, when switching screens or writing text, you would specify the
leopard number.  Any multithreading would have to be done in your ECS
application logic.  Since most of the keypresses in my application will be
stand-alone events, I won't have much need to remember where I am in a
dialog.  The exception to this would be something like getting a password
sequence from a screen set up as a keypad.  It might get challenging to keep
track of more than one password dialog at the same time.

Well.  Those are my thoughts.  What about yours.

Kevin
