Heh. Remember it IS emacs, after all. It IS (or typically includes "out-of-box"
an implementation of) an sh-family shell called eshell.

"""
Eshell is a command shell implemented entirely in Emacs Lisp. It invokes no 
external 
processes beyond those requested by the user. It is intended to be a functional 
replacement for command shells such as bash, zsh, rc, 4dos; since Emacs itself 
is
capable of handling most of the tasks accomplished by such tools.

So, on your average linux install (okay for the pedants, linux is not unix 
exactly,
but emacs works on real unix too) one can do the following (tested, actual
copy+pastes from my system):

# adduser tryme
# chsh -s /usr/bin/emacs tryme
# su - tryme
