I've implemented this (using Regex's, so pushes us to 1.4; it's painful without regex's).

Reading further, turns out there's a second algorithm which is vastly superior. Finding out if the first is even worth adding. Will add the second as RevisedCaverphone.

No answer - but I don't think v1 is worth it. So need to implement v2 instead.

Attaching an implementation of Caverphone 2.0; though due to the similarities between the algorithms anyone can move the code back to 1.0 with easy modification of the source. I don't think anyone would ever want to though - except to compare the two.

Closing as fixed; because I don't think there's any reason to add the Caverphone 1.0 algorithm.
