Ron and All: Please note that there is no prohibition on unpublished codes as long as they are not used for the purpose of "obscuring the meaning" of a transmission. ( see 97.309(b) ) Also note that there are provisions for dealing with situations where there's a concern by the FCC District Director that do not necessarily require that the Ham stop using the code. (see the same section) Also note that there are exceptions under which Hams can use cyphers with the specific purpose of preventing monitoring of the transmission contents. (control of spacecraft) As such, there is no "prohibition of the transmission of codes and ciphers", only limitations on their use.
This means that if the purpose of the scramble code is to preserve data integrity, then there should be no problem. If there's a concern, it's up to the District Director to decide what should be done. In any case, it's not likely anyone would be in jeopardy for doing this.
