I am not shure whether you know that you are responding to a social problem. There is no need for a new implementation as there is a fast and and reliable OSS implementation that uses a license that is compatible with any other license. The Problem is however, that Thomas is not willing to name the fact that he did take an implementation from someone else and that he is not willing to name the author (Heiko Eißfeldt) of this implementation. Heiko did make the first publically available implementation of a CD raw sector encoder 10 years ago and this did take a lot of time using the public information from 1999. Heiko did not only implement an encoder but also a "decoder" (a piece of software that corrects read errors from data with Reed Solomon FEC). Both libraries are available for anyone as part of the cdrtools project. Thomas before did take an old implementation from the same author that was not made available under a OSS license instead of taking a recent version that is under a OSS license that is compatible with any other OSS project and that is even aprox. 10x faster than the old implementation. I am not sure about the background for his behavior......
