I think the holy grail of cloning would be to develop a non-human host for vital organs. The idea is to be able to transplant human tissue without the need for anti-rejection therapy which suppresses the immune system.

Lets say a pig that is somehow genetically altered to be more you than pig and can grow organs. But probably not limbs - that would be very weird. Then again the issue might come up regarding the rights of the pig - is it more human than pig...
