I agree it's something we need to be aware of.  It is a second HTTP 
operation on a presumably already open/cached connection so the TCP and 
server sync costs are reduced.  It is similar to getting CSS or JS from 
a link in an HTML page.

That said, I think the more likely significant cost is application time 
to produce the RDF once the location is known.  This is the same either 
way, with the ordering of the operations being different.
