    Wrap a deferred returned from a pb method in another deferred that
    expects a RemotePublished as a result.  This will allow you to wait until
    the result is really available.

    Idiomatic usage would look like::

        publish.whenReady(serverObject.getMeAPublishable()).addCallback(lookAtThePublishable)
