Intersystem build environment questions

I've received feedback from Harvard. What I want is to be sure that I
understand the concept and can execute it correctly.

I have SSH set up to log into the iMac running Debian. The assumption
is that the script is run on the iMac and it is exported to the
QuickSilver.
Is the SSH setup right? PMac to iMac? Also assume that the script is
run on the iMac and I am running a simple SSH user <at> . Is it
$EXPORTED_ENV to $WORKING_DIRECTORY or $EXPORTED_ENVIRONMENT

ln -s

$USER_BINARY_PATHS?

.
I have Debian running on an iMac G4 and FreeBSD running on a QuickSilver G4.

1. The assumption is that the script is ran on the iMac. Considering
that SSH between both machines is set up, is the exporting:
a) From the iMac to the QuickSilver.
b) The inverse of the above.
And
c) Is it ran from the same terminal used for the SSH login
d) Or from another terminal connected on the target to the SSHed login?

If the exporting is done such as stated in d above, then how do I set
that up properly?
