Can "http://danbri.org" and "http://danbri.org/" URIs represent different things?

Hello TAG,

Talking with some SW folk about OpenID, and whether my "me-the-person" 
URI could be practically usable as my OpenID, I came up with this 
corner-case:

Could http://danbri.org be a URI for "me the person", and 
http://danbri.org/ be a document about me (and also serve as my OpenID)?

As I understand HTTP, any client must request something, so the former 
isn't directly de-referencable. The client has to decide to ask for / 
from danbri.org instead. But they're still different URIs, aren't they?

Is...

<Person  xmlns:foaf="http://xmlns.com/foaf/0.1"/
          rdf:about="http://danbri.org">
  <openid>
     <Document rdf:about="http://danbri.org/"/>
  </openid>
</Person>

...at all feasible? I guess it depends on how exactly we think about the 
"add a / to the end" step...

cheers,

Dan
