I don't understand what you mean by this.  What should the
"Content-Location" be on an http request for the (person)
http://www.markbaker.ca ?  "Sitting in his office chair" ?

I think this is a matter for debate.  People like to link to a company's
web sites in sentences that refer to the company, but this is purely a
matter of convention; any human reading the setence has no problem
disambiguating that the link points to a website while the word (e.g.
"IBM") in the sentence refers to the company.  Nonetheless, what people do
in HTML should have negligible influence on what people do in RDF.

I am quickly coming to the conclusion that there are only two options

  1. Don't use http:// URIs in RDF you author/process/trust
  2. Don't trust URIs to refer to distinct entities

It seems that giving up 2 defeats the purpose of RDF.  So, are we just
left with 1?
