There is a big difference in what happens with rsh or ssh when
your $DISPLAY is already on a different machine than where
the command is issued.  Ssh makes a fake local $DISPLAY on
the remote side that is transparently port-forwarded back
to the machine where the command was issued over the encrypted
connection, then sent on to the original $DISPLAY.  That means
that the server running the window manager that you were
trying to off-load is still involved.  With rsh, your
original $DISPLAY is passed along or you would set it
explicitly to point to the thin client.  Then when the
program starts it will make it's own connection to $DISPLAY
completely independent from the connection where the
command was issued.  Rsh is less secure but off-loads more
of the work.
