How do you get from Longwell to RDF exposed via SPARQL?  In short, how 
does this work when RDF and Longwell don't share locality?

We already have RDF that is SPARQL accessible. The SPARQL Protocol 
allows us to do whatever with the results (including XSLT 
post-processing). The port remains a post processing of SPARQL results 
task. It isn't more than that.
