I think the answer to this is that the main card itself doesn't
"do anything" with the data.  It is the software running on the PIC
which uses the data.

That point may seem a bit pedantic, but since the person writing the
software presumably knows what types of devices he/she will connect at which
addresses, I don't see the problem.  I don't think AID is attempting to
be flexible enough to allow people to plug and unplug peripheral cards
from the bus without modifying the software running on the main board.
(Is that right?)

Rob.
