	thats a dirt simple question Paul.  Reduced complexity in the
	end system.  Check w/ anyone who has run large scale dual-stack
	infrastructure (like ESnet, DREN, SPAWAR, etc) and the one thing
	they pine for is less crap on the endsystem.  Running a single
	protocol stack is much simpler to install, troubleshoot, debug
	and audit.
