No offense, but a spell checking solution that is dependant on someone else's server being around and accessible isn't really the best solution for serious users.

If your host won't support aspell or ispell libraries (which the above "hack" requires), my recommendation is to consider other, more capable hosting providers. They are out there if you do the research.
