	I've done some work on just such a thing.  It works locally, but needs
	quite some finishing off to make it presentable: probably two or three
	full days, without interrupting demands from the day job.  This isn't
	top of my list just now.

	What I've tried to produce is a lightweight display tool which can
	display either the traditional MRTG-generated displays or closely
	equivalent on-demand displays from RRD data collected by MRTG.  As
	far as possible, existing MRTG configuration data is used.  This
	makes it useful in facilitating migration from LOG to RRD format,
	and allows "normal service" to continue while one is learning how
	best to make use of more sophisticated display front-ends.

	Some specific configuration is needed: the web server must be set
	up to provide a CGI interface to the application, and the location
	of the directory where the MRTG configurations live must be 
	specified.  Naturally, write access to the directory (-ies) where
	on-demand images will be created is needed.

	If that sounds useful, let me know; I may become minded to try to 
	give it a higher place on that list.
