Would you ever consider having a "green" funeral?

I was reading an article on cnn.com about a woman that had a dying wish to have her remains cremated and used in an artifical reef. I think this a pretty neat way to memoralize the passing of someone other than just scattering their ashes at sea. What do you think?
