Well, he has replied, and I’m flattered.
Mr. Lambert,
Yes, the story is on the web site. As part of my computer security class, I teach different methods of encryption. My current programming assignment asks students to build a program that automatically decrypts texts written in English. You can see the statement of the problem at http://www.csee.wvu.edu/~cukic/Security. Your text is one of the seven students use to evaluate the decryption performance.
I must have downloaded your story several years ago, but I am not sure where from (it may have been NYT literary section). It is rather a coincidence that I use it for a “geeky” computer science class assignment. I hope you don’t mind.
Regards,
Bojan

Gosh, isn’t the world a strange place? I have found articles of mine turning up in various languages, but never short stories, and never in a computer decryption program! I think that’s rather cool.
So do I! I’m certainly not going to worry about infringed copyright…
