Let's take a look at a plain new CMFDefault site. Everybody without a 
portal_skin cookie sees the default skin. So we don't have to change 
anything for anonymous users.

'logged_in' calls here/portal_skins/updateSkinCookie to set a 
portal_skin cookie based on the member's portal_skin property. This is 
the place to set a portal_skin value based on the users role.

All the following requests can use the portal_skin cookie to select the 
right skin.

'logout' calls context.portal_skins.clearSkinCookie() and we are back to 
the default skin for anonymous.


So AFAICS we just have to change updateSkinCookie (and default / custom 
skin configuration). Or am I missing something?
