You've got it!  The data-product will first be inserted into the
product-queue of system A.  It will then be transmitted by an upstream
LDM on system A to a downstream LDM on system B, which will then
insert the data-product into the product-queue on system B.  Any LDM
systems downstream of system B will be able to obtain that data-product
(providing they've requested it, of course).
