when neji's father was killed, it was cuz the cloud village wanted the dead body of hyuuga hizashi (thats his name rite? hinata's father), and it was mentioned that what they were really after was the secret of the bayakugan......

but i dont get exactly what they wanted to do? its not like they could learn how to do the bayakugan or how to block it or anyhting.......mayb they wanted to do a bayakugan transplant, like kakashi's sharingan (assuming thats what really happened)


any thoughts?
