Well, after our various discussions, I think I understand what this
is about.

I have the following suggestions:

- I think the perspective idea has a lot of merit, however, I'd
   like it to be optional.  In particular, I'd like to be able to use
   CPS Skins without having to use perspectives.

- You said that cells can be filled with portlets or with slots.
   Why not make a slot another kind of portlet?  Then people could
   introduce new slot types and innovations without affecting the
   rest of CPS Skins.

- Use of the term "portlet" here leads to confusion with JSR 168
   portlets, which are different.   I would prefer to see a different
   term used for what CPS calls portlets. Absent that, we'll need to
   find some modifiers to disambiguate.
