I'd like to make some substantive comments on the proposal.  My initial
reaction is that the solution proposed is very complex and I'm not at all
clear about the problem it solves. :)

I think I need to understand how themes work in CPS skins.  In particular,
I need to understand the relationships between themes, pages, sections,
cells, global portlets and local portlets.  Your proposal is based on
but doesn't really describe most of these concepts.  Can you recommnd
some documentation?
