From the article: Rack is a web server interface and software package for R. It is very much like Ruby’s Rack. In fact it is so much like Ruby’s Rack that I decided to use the same name and basic class hierarchy. You could say I “borrowed heavliy” from Ruby’s Rack, and you wouldn’t be far from the truth. In fact, you could say “I stole their idea” and re-purposed it for R, and then you’d be telling the truth. If you're going to totally copy a concept (which is fine, this is all OSS after all), at least derive a new name for it.
