Never heard of this having a unique version for programming or development. These days, I suppose most "user names" are kind of like this for programmers and the necessity to not use the "same identity" in order to use most websites with a login service basically means you're SOL with coming up with a name that multiple people can adopt.

The closest we have is the hacker-worlds "Anonymous" or similar hacking groups where it's always unclear if it's one person or multiple in actuality.
