In reply to your p.s., yes, I meant REFERENCE, not REFERENCEABLE.

Here is what we are trying to accomplish.

We have several "sites" {Public, Local, National, Press, etc...} and wanted
to use separate workspaces for each one in order to segment the content. 
However, occasionally, content from one "site" must refer to content from
another "site".  If we implemented this using workspaces, a node from one
workspace will need to refer to a node from a different workspace.
