Inline Spell Checker JavaScript Access

Is there any way to access the inline spell checker XPComponent from
JavaScript?

Using Firebug, I can see the component listed under editor, but access
is denied to it when I try to use its API from JavaScript. I want to
be able to programmatically detect misspelled words and get the
suggestion list.

I know this is an odd request, but I have my reasons... :)

Thanks,
Wil
