I suspect having version 3 followed by 3.1, then 3.14, and so on up to 3.1415926[...] would be TOO obvious, and make the whole thing too "cutesy".
So are there any other kewl only semi-famous numerical constants one could use in stead? (Avogadro, Planck...?)
Oh well, maybe the whole notion of copy-catting the idea is too pathetic in the first place... :-(
