I implemented this today by dropping in a new CatalogTool subclass. 

I've got 'Sites' inside each portal, which are portal-like objects.
Each defines a getSite method, something along the lines of
portal_url.getPortal(). 

I added a 'Site' index to the Catalog (in the enumeratedIndexes
method). 

Every time an object is indexed, the catalog_object method wraps the
object with extra information.  I added the line 

  vars['Site'] = object.getSite().getId()

to this method, so every object is now always indexed with a Site
name.

Then in the searchResults method, I added an extra criterion:

        if hasattr(self, 'getSite') and not _checkPermission(
            ManagePortal, self):
            kw['Site'] = self.getSite().getId()

Tada!

If anyone wants the whole Tool, give me a shout.  It's dead simple.
