Off topic: I used to know a guy named Ithkuil. It's not a common name in North America, but it is definitely a personal name. I know how strange it is when you find a random software project. Send after you. There are at least a couple named "Igor" out there.
Are you sure they weren't actually named after the language? I have been using it for gmail for many years (just because I am a fan, not connected to the language other than that).
