/**
 * This interface is used by {@link IRemoteFile#listRemoteFiles()} method
 * 
 * Clients implementing this interface can either export the implementation
 * using {@link UnicastRemoteObject#exportObject(Remote)} and then
 * the server will make callbacks to the client to perform the filtering.
 * This method will be slow! (Every time the server needs to check the file
 * it will make a remote call).
 * 
 * If the implementation's instance is not exported, it will cause the
 * class code to be run on the server which requires some extra caution
 * with client's codebase and raises security considerations (server 
 * running client's code).
