	First, I said that if you only had one PF running, you could see
yourself, but if you had multiple PF's running, you couldn't.  Then, various
people said that didn't make sense,  Then I recanted, admitting that I
couldn't reproduce my results.  Then:

	Aha!  That explains it.  The full order of events was as follows.  I
installed PF on my own II-cx and could see myself.  Next, I installed it on a
friend's Plus.  I could see the PF running on my II-cx downstairs, but no
"myself" on the Plus.  It was at this point that I jumped to the conclusion
stated above and posted my original article.  Just further proof that it's bad
scientific form to try and form a conclusion from just 2 data points.  When I
said I couldn't reproduce it, I had just finished installing PF on two other
II-cx machines, which could see themselves (as well as the Plus), causing me
to doubt my original observation.
