If you are in a hurry you may get frustrated with Zope.  It has a wierd sigmoidal
learning curve.  Easy to just add html and simple dtml to do things like common
headers/footers.  Then you try and do something a bit more complex and you find
you have to deal with dtml quirks, acquisition, and not-particularly-well documented
internal interfaces.  You spend a lot of time digging around the .py files in Zope.
You get angry.  Then you amass a critical amount of understanding and things fall
into place.  And things get easier, and more elegant.  (I'm just starting to be
able to see this level of understanding in the distance).

My suggestion?  If you need to get an intranet thingo going in a hurry, use the tool you
know the best,  cgi, mod-perl, whatever.  But set up a zope server (really very easy)
and try to spend a little time each day learning one new zope thing.  And one day,
someone is going to ask you to add feature x to your mod-perl scripts, and you just
might say "the heck with it, it would be easier just do do this in Zope".  Or mabye
not.

Don't underestimate the power of the permissions system in Zope.  If you have
any sort of collabaritive(sp) site, you're going to need user classes and
permissions, and Zope's got it built in.

NB  We are using Zope internally, and are pretty happy with it, but not yet for 
external prouction systems.  Mabye someday.
