    Isn't that a little dangerous?  Your finger daemon won't finish
until it's fingered the other person.  What if you finger yourself?  How
about somebody else running a similar system?  I've seen other people do
similar daemons.  An enless loop of finger daemons would not be
pleasant.  To be safe, you'd really need to put a check in there to see
if the same site was fingering you again, or something similar.  At
least, I think this is true.  I've never written a finger daemon so I
may be completely and totally wrong.

I used to live in England, and my parents still live there.  As a
present, my dad sent me a Newton (special sale deal, etc.).  One nice
thing that the Newton comes with is a universal power supply.  However,
universal power supplies don't have universal plugs; it only had the big
British plug on it, and no removable cord.  I didn't have any type of
adaptor handy, and the batteries in the device were going down rapidly
(playing with it all day).  So, I needed to make an adaptor...
I took two fuse clips (coincidentally from a British plug) and stuck
them onto the two AC power pins of the Newton power supply (the clips
needed slight bending to fit).  I attached short pieces of speaker cable
to the clips.  I then took two paper clip halves and bent them just
enough so that they would fit securely into one of those IEC removable
computer power cables.  Next I soldered the speaker cable to the paper
clips.  Finally, I taped a piece of blister pack on top of this to
insulate it.  It was messy, but it worked for two months until I went
back to England and picked up the appropriate adaptor.  I now have a
completely safe and boring power connection :(
