@manuboss, I'm sorry I didn't reply to this sooner. It is possible to use Captcha Breaker currently, you just have to set CB to emulate one of the pay per solve services and then set NHSEO to use that service and CB should intercept all captchas sent to that service.
Also I know this has been requested a lot but as of the update I am uploading now users will be able to set a secondary captcha solver for when the first is unable to solve a particular captcha. This will allow people to use Captcha Sniper or GSA CB in conjunction with a pay per solve services to maximise links.
