ssh is tunneling the X packets internally. While it takes a little
longer, it does ensure that you are not sending unencrypted data across
the network (which could include passwords, confidential documents,
essentially everything you see or type in your X session). This is
generally considered to be a GoodThing (tm).
You /should/ be able to do something like:
xhost +<other-box> <-- on sampsont
rlogin <other-box>
setenv DISPLAY=sampsont:10.0 <-- on <other-box>
However, this then sends unsecure X data back and forth between sompsont
and <other-box>. Easiest is to use SSH to forward the packets back and
forth, either from your mac to <other-box> or from sampsont to
<other-box>
