Regarding the "#", I don't see that is broken from a service provider  
standpoint. Could you please detail the awkward or no possible  
features you re thinking about.

I suggest using "#" as a fragment identifier separator because:
- It is easy resolvable in an HTML page, since it will refer to the  
anchor, an those we can easily display information about a resource.
- If I publish and ontology and give the URL to a semantic web tool  
it will understand the "#" as a fragment separator. And I can publish  
the ontology in the base URI (String before the "#"). The way you are  
suggesting will confuse semantic web tools.
