 This is not yet supported by IPython, but you could implement it with a
custom KernelManager, though I would not actually recommend doing that. At
this point, the notebook is a fundamentally single-user application, where
the notebook server and kernel are the same user on the same machine. There
are tools like ipydra <https://github.com/UnataInc/ipydra> that spin up a *
server* for each user, which is likely the simplest way to go for now.
