The Lootable Bodies mod for 1.8 spawns a body after you die. This body contains your items and is unharmed by fire, explosions, and falling.
When you die, this mod spawns a corpse and puts all of your inventory on the corpse. Damageable items suffer some damage, but will never be destroyed. Nearby items on the ground will be sucked into your corpse too.
Protects against lava:
Hitting a body 3 times with a shovel will dispose it, dropping any equipment it has still on it.
