I have a remote box, hosting some SAP drivers (alas, I have zero access,
must go through hosting company, and it is painful) and i need multiple
Remote Loader instances.

Using the thin Java Remote Loader, I have two conf files right now,
different ports, different classes, different logs.

I know I need to run it as
../dirxml_jremote -conf Conf8000.conf -sp remote driver

to generate the encrypted password files:

But my question is, if I wish to run two, can they share these? And
thus the same remote/driver passwords (Which is fine for us security wise).

Or do they need to be in different directories, so each can have its own
pair of password files?

I have never entirely understood this encryption method, so curious to
hear what folk have to say.
