(3) use a protocol-independent way to communicate the document's URI;  i.e. 

The requirement I was imagining was not necessarily to preserve 
persistence, but to provide a way for cross-referencing between multiple 
transient subgraphs.  I.e. to reference resources defined by rdf:ID from 
outside the document.
