Clay, that's a good question. I would just reuse a implementation I
currently have, which uses for a key to look for a valid solution in a
database:

<input name="captcha_key" type="hidden" value="ccb53...long hash...5902" />
<input type="text" name ="captcha_solution" value="" />

When the form is submitted, that row in the "captcha" table is read to
check if the solution matches. I haven't looked for other
implementations; and now that you asked... perhaps only the hash would
be enough?
