Semi-public resources in Uniform Messaging

I'm trying to understand this proposal and how it would interact with 
Server-sent Events, XBL2, <canvas>/<img>, and <video>:

   http://lists.w3.org/Archives/Public/public-webapps/2009OctDec/att-0914/draft.html

How would one label a static resource on an intranet server, e.g.

   http://videos.corp.example.com/tgif/2009-12-11.ogg

...such that it can be used by the pages on the following hosts:

   http://www.corp.example.com/
   http://moma.corp.example.com/
   http://tgif.corp.example.com/
   http://intranet.example.com/

...but such that it could _not_ be used by pages on the following hosts:

   http://hostile-blog.example.com/

...?

Things that are impossible just take longer.   `._.-(,_..'--(,_..'`-.;.'
