Integrating this into ConfirmEdit extension shouldn't be hard. It's the
extra features what makes this tricky. This system is interesting for
gathering translations, but doesn't work for verifying that the answer
is right. How would you verify that?
The approach that comes to my mkind is to show both the current captcha
plus another, optional, captcha, with a note about how filling that
second captcha helps wikisource, and that the answer will be logged with
ReCAPTCHA already works in a way similar to this. Two words are
presented but only one is known and actually serves to filtrate
accesses. They then collect answers for both words and if the test on
the first is passed (which indicates a human) then the answer for the
second is recorded. When a certain number of people agree on the
transcription of a previously unknown word then that transcription is
taken as good and used in future as a filter word.
We could say that we accept a transcription as "valid" after N people
agrees on a given word and put back on Wikisource only the validated
words (and also use them as filters, too) . This seems both a reliable
and easy-to-implement system to me.
Anyway, at the beginning we could use the system you describe using
the current captcha and words from books.
I believe the trickiest part is creating a system to put results back
in Wikisource in a semi-automated way, but having "captcha reviewers"
We could also decorate our captcha with "this captcha helps
transcribing <BOOK TITLE> + link".
And this leads me to what I think is the real point: once we have a
basically-working system we can think to whatever useful feature and
implement it, in principle we can have a modular system which can be
refined /at libitum/.
