In general, yes. There is a way that an upstream site can send a data-product 
to a downstream LDM server "out of the blue", but that mechanism is seldom used 
because it is much less robust than the standard mechanism.

Can you do a notifyme(1) on the downstream host to the upstream LDM? Execute 
the command "man notifyme" for information on that utility.
