I didn't read the first part of the proyect, Sorry ;) By the way I've read the documents maintained by Michel K. Neylon and I think that the content, grammar and data of the messages are very "human-like". For example: It contains the number pi (even in its base6 form) but thats the relationship of the perimeter of a circulus into its diameter, but other races (or kind of inteligence) could define as the relationship of the area of a circulus into the area of the square that contents it. Other things make the interpretation of the data inconsistent such as thinking that the only inhabitable planet is the first one and in a later message y says (or we think) that the are others planets with life.
