I'm not entirely sure why people would seek to produce cloned meat commercially. At least with how cloning goes so far, it has produced genetically inferior animals with more illness and weaker immune systems, when the animal makes it to term at all.
I see plenty of reason for genetically modifying animals though, and for producing meat in a petri dish (skipping the animal altogether), but don't see why the conception method (cloning in this case) is so important, particularly if it still has to go through a normal gestation process.
Of course, once the normal gestation process can be skipped, via artificial wombs as are currently being developed, mass production could take place on a whole new scale.
Oh, and I suppose there is one case in which cloned meat would be quite interesting: think cloned wooly mammoth. It sooths the caveman soul
It'd enable people to eat endangered/extinct animals with little guilt.
