	On an ordinary Unix machine, eg a Sun, it is possible to pretend,
	using NFS, to be any user one wants to.  This requires about as much
	skill, especially under earlier releases of SunOS, as re-setting
	the uid/gid in Amiga TCP/IP.  It is hard to provide real authentication
	on a machine that does not have a protected memory address space.  
	I've heard that the PC implementations of NFS have this same problem, 
	even though some use pcnfsd to authenticate a user.  Security that
	is little more than an illusion is perhaps worse at times than no
	security at all.  

	As I recall the timeline, we've had NFS running on ethernet on the
	Amiga since roughly 1986.  Since I don't follow the NeXT, you can
	figure out which existed first ;-)
