I just finished a book called Speaker to the Dead, by Orson Scott Card. It was an amazing book and has become one of my favorites. It is mostly about how the human race would interact with an alien species after they had annihilated the first alien species they encountered. Buried within the plot of this book though is a very unique idea on funerals called a "Speaking." It can be done when the person dies or even years later. The Speaker learns about the person from friends, families, enemys, everyone. Then he speaks the truth about the person. He talks about their faults, their goals, their accomplishments, their unspoken sins, and secrets. He reveals everything no matter the pain it would cause to those left behind.
Anyways thought it was neat..
