A subtle meaning to plone4artists? :-)

Excellent idea.  I guess I got so hung up on the issues raised on
plone.org about <html> tags, etc. that I didn't even thinking of
wrapping the whole thing up in a page template.

However, I don't think this is going to work for the navigation tree
although I have to check to make sure.  The problem there is that it
*is* dependent on "here".  I suspect there is an intelligent way to
cache it, but I suspect it would have to be broken into two pieces.  One
piece would grab the file system structure and the other would render
the tree (including any children and the bolding which is location
specific).
