Re: Adding ispell-multi.el and friends to Emacs

    No.  I see now that modifying and testing all of the functionality of
    both ispell and flyspell to work consistently with multiple ispell
    processes may take some considerable effort, and I have other things on
    my plate at the moment.

In that case, we should install your code soon, thus
giving someone else a chance to do the rest.
