I wouldn't call it "asking too much" - it is rather an absolutely 
reasonable request. So let me explain a little more:

The Webapp has only one page with a textarea input field, where you can 
enter RRD graph arguments. The graph then gets generated from the 
resulting commandline and is displayed on the same page. You can then 
interact with the graph.

I did not put it onto one of my machines for the following reasons:

* it has no security, currently (you have to use some "DEF", accessing a 
file on the server, after all). Thus it requires at least one RRD file to 
be around - and that should have "recent" data. So I would need to add 
some RRD file update mechanism... 

* if the general public would access such a demo, it might become a CPU 
nightmare on that poor machine. 

* plus the demo is much less impressive if there is some high latency 
network in between the server and the browser. So you should really try it 
on a LAN


So - for the time being, I really cannot give you a "live" demo 
installation...
