How does mixing and matching kernels in one notebook work? Can you directly exchange data between cells of different kernel types somehow? Do you go through the filesystem or some kind of in-memory serialization?

(I'm sorry for the questions that could be answered from documentation, but I can't find the docs on this feature! I have been wanting to specify data cells in a notebook, like the markdown cells, and then reference their contents from a code cell)
