I see your points.
So, to get a cross-publication search, one could either

   - configure the pubs to use the same index or

   - build an aggregating search (probably by extending the
     SearchGenerator to search multiple indexes and merge the hit lists)

Do you think that cross-publication asset and link management would be 
nice to have, or do you consider it unnecessary?

Thanks for your comments!
