Thanks.

Cool.  If they are in any way based on OS/linux mechanisms rather than 
application mechanisms please consider submitting to munin-exchange at 
least.

Not really.  Munin-html simply creates a statical html document 
hierarchy and links to the graphs.  Unless you can make a 
group;host:plugin hierarchy that matches your user separation this is 
not a match to your needs.

Maybe.  See munin-update/graph/html/limits --help
