I'm sorry, but your message makes little sense to me.  While it's
clear that you can switch back and forth between environments at
the user level, and define some syntax to specify which one to use,
it's not so clear how to make the facility available to user and
program in a clear, well-defined manner without re-writing every
program ever written.  The problem is how giving the user the
environment he wants whenever he is active without simultaneously
blasting existing programs whenever he changes his path, not
defining shell command syntax.

P.S. With multiple window support, or job control a la "csh" you
can have environments running simultaneously anyway.  Just start
up a new shell, define your new enviroment, and visit at will.
