This has been suggested before and I'll add to this what I added to the previous suggestion ...
Great idea, but make it user switchable. To be forced to have something on, like the uncapitalised sentance rubbish in 7.31's spell checker, with no option to turn it off is awful.
I for one don't want auto-spell checking, but I can see the use, so with it there and selectable as an option, great!
