Aether Rift rulings:
2009-10-01: First, the card is discarded. Then, in turn order, each player is given the option to pay 5 life. Then, if no player paid 5 life, the card is put onto the battlefield from the graveyard.
2009-10-01: The card is actually discard, so anything which triggers on a discard will trigger. Such abilities will wait to go on the stack until after this ability has completely resolved.
