this implies that you are domain owner of www.whitehouse.gov if you make
up this fictous resource. 
F.E. I have stated on http://www.gnowsis.com/wiki/GnowSis/LeoSThesis to
use this uri to identify the thesis, although not the pdf can be found
there. This may be good social practice, to tell people what uris to use
for identifying concepts. State on your homepage which resources are

if your applications run only on a local context, they may only use
local uris, then your problem is also solved:

you then configure your "distributed querying engine" to ignore these
local uris and contact the server directly. 
And about highly used public uris (like f.e. the RSS schema):  You can
also assign "alternative sources" to these resource, 
f.e. "http://purl.org/rss/1.0/*" can be found on my local host database.

I would recommend that you are only allowed to make up URLs using
domains you own!
