No.  Unless you build a means and tell the parser to invoke 
it, an FPI is a dumb string.

A URzed is always dereferenceable.  If we accept that, then what 
we call it and the semantic issues go away.   One will 
get back a document (RDDL, XML Catalog) or just a 404 
document.  The list there is what the fuss should be about. 
But as long as there is a protocol morph on the front of 
that string, the system says, "I can dereference this because 
the string says I can unless you say I can't" and how do we 
tell it not too?

Enough philosophical ostrichism.  It is ALWAYS dereferenceable.

However, if it is at least reasonable to look at URLs as identifiers, then I 
think that all the problems you, Len and Simon state are unfortunate, but 
merely the symptoms of the choices of one arbiter of URI usage (the W3C), and 
not a symptom of fundamental uselessness of URIs themselves.  If we'd gone 
with FPIs instead, we'd have the same problems in variant forms.
