Yes of course.

The problem is the current mechanism _forces_ the user to have
different environments on the same box - there's no choice.

Which is, as Al says, just like environment variables.

But not like files - if I create a file called $HOME/foo, I expect
that I can access it from a different login.  I might want to have
different environments, but that's not the _default_ when dealing with
files.

The question is whether private user-mounts should, by default, behave
more like environment variables or more like files.
