  programs use it. The reason is robustness: in order to ensure reliability, 
one would have to wrap these programs with sufficient error-checking and 
contingency-handling code as to, basically, recreate the LDM server.> We are

That's correct: you would not need to run an LDM server on the upstream host to 
do what you want.

What you want, however, will not be as reliable as running an LDM server on the 
upstream host and requesting the data from it by the downstream LDM.
