[Zope] Same product in multiple instances automatically?

The one possible "gotcha", dating back to the Zope 2.6.x / CMF 1.3.x days,
is that CMF (and Plone) would not work properly if installed
somewhere other than $INSTANCE_HOME/Products.
The skins directories wouldn't work for some reason having to do
with DirectoryView.py.
I don't remember the details and hopefully this has been fixed since
then; I haven't tried that particular scenario in a looong time.
