Sure the client-side behaviour of "Use Ajax to do spellcheck via a
WebService" is easy enough.  But how does one implement the
WebService?

If you build a solution that handles only a single word because that's
all the current design requires, how well will it scale to a solution
where the user is typing a whole sentence?  .. or if the input is
changed to a textarea (implying potentially MUCH more text than a
single word or sentence)

Del's use was for a quiz.  I wonder how many teachers accept
incorrectly spelled answers as "good enough" for full credit.  Is this
a nice-to-have or a need-to-have feature?  Are the quiz answers likely
to be found in a dictionary of standard english, or are you going to
have to add the answers (and potential misspellings)  There are a lot
of considerations.
