Lots of things: bytes, bytearray, memoryview, array.array, NumPy arrays, just to name a few. Basically anything that wants itself to be representable as a chunk of memory with metadata. It's a very common thing in the Big Data department (although many people wouldn't know that they're actually heavy users of this protocol because they just use NumPy and/or Cython and don't look under the hood).
