It's far more frightening to me that they may be serious. If so, they are really a scary group of people.
I am all for people doing what they like with their corpse. I loved visiting Bodyworlds last year and have been interested in that exhibit for years, long before it came to the states. Those people chose to donate their bodies to science. I also attended a cadaver class where we worked with a corpse that had been donated- again, for science.
However- some of the info on that site implies that they do not plan to tell consumers what they are eating.

Where Will My Flesh Go? Who Eats It?
Your flesh would go to a grocery store or fast food chain where it would be prepared in a wide variety of forms and sold to individuals who would otherwise be consuming animal flesh. We've received questions from prospective donors asking whether or not they would have control of who gets their flesh. Unfortunately, it would be very difficult to allow donors to choose who actually consumes their flesh, as this would mean donating bodies directly to consumers. This poses a problem, because most individuals and families lack the knowledge, skill, and desire to butcher their own meat. The vast majority of people prefer to alienate themselves from the entire process by which meat is produced. People want to see the flesh they eat only in its final form, neatly packaged and bearing no resemblance to a living being. This being said, the only practical control that donors would be able to exercise would be which participating restaurant, fast food chain, or grocery store would receive their flesh.
