Either it's going to go to a well-known centralized server of RDF 
information (i.e. a semantic web Google), or it has to get some hints 
from the context.

There might be something in putting more hints into the context: When 
you publish RDF, your RDF should have enough information so that 
consumers can locate more information over the web about every resource 
mentioned.

<foaf:Person rdf:about="some_person">
  <foaf:knows>
   <foaf:Person rdf:about="some_other_person">
    <rdfs:isDefinedBy rdf:resource="uri_of_authoratative_data_source"/>
    <foo:mentionedIn rdf:resource="uri_of_other_data_source"/>
   </foaf:Person>
  </foaf:knows>
</foaf:Person>
<foo:DataSource rdf:about="uri_of_authoratative_data_source">
  <foo:sparqlByHttpGet>http://foo.bar/foafserver?q=</foo:sparqlByHttpGet>
</foo:DataSource>
<foo:DataSource rdf:about="uri_of_other_data_source">
  <foo:availableAt>http://bar.foo/foaf.rdf</foo:availableAt>
</foo:DataSource>

Basically just making seeAlso's richer by explicitly providing queryable 
addresses.
