I don't really see the point in it unless it's some religious deal where you think they can't get into heaven if their earthly body is destroyed or some thing like that.
Personally I'm an atheist and don't believe in an after life, once I'm dead I don't give a shit what happens to my body and I don't see the point in visiting graves (I never do). I can remember those who I knew and died without a body in the ground. If you really need it cremate it and put it on your mantle or something, otherwise just throw the ashes over a cliff or something.
Interesting related fact, some Tibetan Buddhists cut up their dead and feed them to vultures.
