    A C++ interface wouldn't be all that different.  If the (elisp level)  
    spell-checking package provided clear separation between UI and  
    accessing the spell-checker (the API that I'd like), then support for  
    other spell-checkers could be implemented easily.

It is a very bad idea to link other appls such as Aspell into Emacs.
It would cause constant maintenance trouble.  So we definitely should
not do this.
