No, absolutely not.  That is as wrong a perspective as possible, so if
you still think that then somebody needs to make a screencast.

I know about that, but I would not call it "easy".  There are subtle
issues, e.g., where on the host's filesystem should Sage store its
files.   There are also issues with getting it to actually work in
practice robustly.   But it's probably the best approach given how the
notebook currently works.
