Could you perhaps elaborate on the what this theory might imply with regards to transmitting genetic information?
The most obvious implications would be in relation to the likelihood of changes in the genetic 'message' due to the 'noise' of random mutations, specifically in terms of the transgenerational transmission of genetic information.
Are we (evos) being disingenious when we state that the creationists won't or haven't yet defined information (IOW do they actually use the definition presented by Information Theory and can it be applied accurately to genetics)?
No, creationist and ID proponents do not simply refer to Shannon information or Shannon entropy in their arguments. That doesn't mean that it can't be applied to genetics however and indeed it has been in a number of ways, including searching for regions of genetic complexity, and it has been shown that there is more shannon information in genomes than in an equivalent set of random sequences (Chen et al, 2005).
Someone whose work relates to information theory and who has often been co-opted by anti-evolutionists is Hubert Yockey. Yockey has argued that there is reason to doubt whether we can ever fully understand the actual processes which gave rise to the early life and proto-genetics which preceeded life on Earth (Yockey, 2000). Yockey has also put forward some calculations of the kind creationists love regarding the probabilities of Cytochrome C forming spontaneously . Yockey has made some explicit analogies between Shannon information theory regarding communication and elements of the processes involved in translation and transcription. To see how one creationist approaches Yockey's work go here.
Other Id proponents prefer making their own definitions of information up such as Gitt's form of information which has its own thread, The value of Gitt information.
William Dembski starts with a similar calculation for information as Shannon but uses a different definition to fit in with his own ideas of complex specified information which seem to involve conflating shannon information and another measure known as Kolmogorov complexity.
