Does anyone know if this trick still works with ReCaptcha?

Make a program to make a POOL of decoded recaptchas.

So there are 2 programs you have two program A & B.

program A will need solved captchas in 5min. At every checking, it will ask B to offer a decoded captcha.

B will run at background and grab captcha from recaptcha and decode it with a captcha service, then put all decoded captcha into the POOL. When A asks a captcha from B, B will get one from POOL and send it to A. When there is not enough captcha in POOL, B will make more.

Thoughts?

Reply or PM please!!!

I don't understand what you're trying to accomplish? Crack recaptcha?

This isn't how recaptcha works.

EVERY image that you get served with recaptcha is UNIQUE.
It is comprised of two words.
first word is already known to google. It's only there to identify you are really typing the correct word. Second word is the one you still need to decypher (from google's document scanning). After certain amount of inputs it gets placed onto "known list" and will be displayed as 1st word.

Your program would make sense with original captcha, not recaptcha.

if I understand correctly, you want to cache the captcha result? it will not work. each image is unique and there are so many possibilities, there is no simple way to do this.

Won't work. Captchas time out (are removed form their database) after about 5 minutes or so.

This would, however, work for badly implemented captcha challenge systems. e.g. phpBB. Although for most you can just replay previously solved captchas.
vBulletin's own system (not reCaptcha), for instance, have a better implementation.
On my spam scripts for vB I made it download+display the captcha image and display an input box for it, then submit.

recaptcha system already compromised they have one real weak point the images they show there database known only one word from 2 words they show ... and more over the word they know they wont verify the end letter .. more then enough to create ocr with proper coding skills

It is not all about coding skills, it is all about algorithms.

Short answer, that will not work. OCR is the only solution, but its very expensive and not 100% occurate

It seems a good idea unless this is true. If the captchas timeout then there's too small of a window to have the benefit you are looking for
