you might be right,
is is an overkill when you start. just creating a new folder and a new 
plone site in it is *so* easy.
however, every site has its own lifecycle and tends to call for extra 
products, adaptations, plone & product versions, you name it. every such 
change affects every site in a "one zope/several plone site" setup.
and even if the change migth be trivial, it can have unwanted side 
effects for an other site.
my experience is: dont do it!
