Kosher Peating can be done minus shellfish- you could still eat small fish. Guidelines about separating milk and meat isn't really that much of an issue. Kosher regulations on certain cuts of meat(I've met Jews who do not eat flank steak or any cut from the back half) may be tough(no oxtails) but you can still eat bone marrow, the feet, and front half joints.
Halal Peating seems easy. My understanding(limited) of Quran and seafood is that seafoods, including shellfish, are allowable so long as they do not resemble a haram land animal to eat- sea snakes, alligators, crocodiles, fish that look like a dog/human are haram. I'd love to try camel or desert goat milk- i hear camel milk is very tasty and can be minerally.
