So what?  Should relative URLs still be correct? I guess that what
you want is absolute URLs that (mostly) don't depend on context.

I'm not sure what ZClient has to do with it.

I guess you want a navigation bar in a standard header
or footer that provides absolute URL to some standard places
that don't depend on where you are. Right?  I think that
the 1.10 absolute URL machinery (absolute_url method
defined in SimpleItem.Item and therefore in all framework
objects) should make this alot easier.  We'll put together a
demonstration of this.
