	Most of these seem to offer ftp access only (using "sticky bit"
	directories - and/or possibly wu-ftp "guest group" facilities)

	If you insist on allowing telnet into it (and poviding a shell
	account) you might look at the 'restricted shell' (I think there
	is a command line option on Bourne or Korn and support for 
	it automatically assume this option if called via the name
	'rsh' -- i.e. via a hardlink).

	The restrictions an this 'rsh' ('jsh'???) are something like:
	can't change directory, can't set/unset any variables, can't 
	create any shell functions or aliases, etc.

	If you find out more (like an FAQ on them) I'd like to 
	hear about it.
