I dunno. But looking up the info page, I see:

	Invocation

	* Restricted Shell::


	Restricted Shell
	================

	When the basename of the command used to invoke zsh starts with
	the letter `r' or the `-r' command line option is supplied at
	invocation, the shell becomes restricted.  Emulation mode is
	determined after stripping the letter `r' from the invocation
	name.  The following are disabled in restricted mode:


So the answer is yes ;-)

I think you simply have to hardlink rzsh to zsh - as a matter of fact, 
bash uses the same trick:

lrwxrwxrwx  1 root root 9 2004-08-15 14:04 /usr/bin/rbash -> /bin/bash*

Well, with a softlink.

I'm not familiar with traffic shaping, I don't know. Perhaps if he uses a
fixed IP :-? - in that case, I would also restrict the firewall so that it
is only possible to use ssh from that IP.
