I suspect that's good because the original poster specified a TCP/IP connection 
for DDM.

Correct. But if you want a secure system, it's not especially easier.

IBM is the only source I've heard say 'DDM client' until recently. In APPC 
environments, the terms 'source' and 'target' were used. As TCP/IP and 
client/server became pervasive, we also got the 'DDM server' which implies 
'client'. Under OS/2, I saw it referred to as a DDM client to AS/400s. From an 
exit program point of view, there are clearly client requests sent to the 
server.

I can't recall my first use of DDM, though 17 years isn't a bad guess. I know 
it wasn't on 1401s when I started with those.
