That's correct.  The downstream LDM process receives the data-products
that it requests from the upstream LDM process and writes them into
the product-queue.  It doesn't do any processing of the data-products
itself: the "pqact" processes do that.

The upstream LDM process sends all data-products requested by the
downstream LDM process to the downstream LDM.  The data-products
requested by a downstream LDM are set in the associated REQUEST
entry in the LDM configuration-file (etc/ldmd.conf).
