Hi Chris,
Normally I'd say something like that could not be done, but you may find a
clue in http://support.microsoft.com/?kbid=257643. By excluding certain
users' access to the registry keys listed in that article, you might be able
to disable spelling and grammar checking for them.
I suspect, though, that it would work only if you're using Word 97, and that
Word 2000 or later doesn't follow the same rule.

This works quite well.
