Thank again :-)

I'm looking at the options right now.
Not a Zope problem so I guess I'll look in the python community for answers
:-)

But MAYBE someday I'll be back with a Zope Product that quieries the SNMP
and displays all sorts of things ... hmm .. perhaps using mrtg ?

Well I dreaming right now - too busy developing other Zope stuff. But maybe
when I have a holiday :-))

Good night - Gitte
