I haven't seen it before, but I have thought about it. I decided not
to implement it. Why? Think about it. What if my fingerd and theirs
both implement this "feature"? How long they will keep fingering each
other?

Or if I find another internet site who implements this, say
rixrax.foo.com and give command

finger @tiger.nrl.navy.mil@rixrax.foo.com

and let them finger each other forever.
