So, the OS X box is the firewall? It's just reaching out into the badlands
and getting the files to deliver to the safety of the two YDL machines? It's
still not clear to me the topology. You said the files are generated on the
Mac OS machine but you then said it had two NICs.

If security is still an issue, I don't see it if the scenario is as I
picture it. The insecure files are being tranferred to machines on a secure
network. The problem would be the first step, getting the files securely off
the machine that's generating them.

Where is OS X?

File Generator ---- Firewall ---- YDL boxen
^^^ Here?

or is it parallel to the firewall:

                 +- OS X --+
File generator --|         |- YDL boxen
                 +-  FW  --+

Or do I have the YDLs in the wrong places?
