Even more, I wonder how many people use RemoteSearchable in real 
applications. If it's in a relatively small number of cases, then let's 
move it to contrib - so long as we remember to keep all search-related 
core classes Serializable ;)

I recall a single situation when I had a use for remote searchable, and 
due to the operational issues with running rmiregistry we went with a 
custom RPC anyway.
