The name was a bit of a coincidence.
We first decided on Planetaruim, but the domain-name was taken (shock!).
Then I got the idea of mixing up Planet with some kind of military rank..Came up with the old roman title Centaurion, ditched the "u" as it sounded odd, and hey presto...
As for old code, um, naah, I might have bits and pieces, but nothign worthwhile.
