Cloned meat should be kosher as long as the animal is a kosher animal (split hoof, chews the cud) and as long as it is properly slaughtered by a trained kosher slaughterer (shochet) and soaked and salted according to the halakhah (Jewish law). There should be no difference whatsoever in terms of kashrut. I can only assume that the same would be true for Halal, since in general, the Muslim meat laws are less strict that the Jewish laws of kashrut.

I personally would have no problem either drinking milk from a cloned cow or eating meat from a cloned animal, so long as it was only cloned, and not genetically modified in any way. And that's both in terms of my own standards of what is and is not gross, and my understanding of kashrut. Because in terms of what is kosher, just cloning an animal should mean nothing. But when you end up with cows that glow in the dark, or sheep that produce squid ink, or goats with lobster claws instead of testicles and such, I'd have to doubt whether such creatures were kosher under the laws of kilayim, which forbid Jews from partaking of improperly hybridized combinations (no joke!! See Deut. 22:9-11 and Num. 19:19, plus a whole tractate of the Talmud dedicated to the resultant laws of kilayim and shaatnez).

Finally, for the record, I laughed at the Gwen Stacy joke. Probably a little too hard.
