[Zope] Portal system similar to my.yahoo.com

[boz@home.com]

Hi all,

I'm looking for a good base to build a portal system and wonder if Zope 
is it. Basic requirements are...
    - my.yahoo style home page feature without all the news feed stuff, 
just our own widgets in portlets.
    - portlets can be added/removed by user.
    - user accounts with roles limiting which portlets may be added.
    - skinnable

I've looked over some of the docs for Zope and CMF. What I haven't seen 
yet is a description of how to set up an editable home page with 
portlets. Is Zope what I'm looking for?

Thanks!,
boz
