I'm using 68 Classifieds on my site with a reCaptcha module. This project is to create a module that hooks into the 68 Classifieds system for Solve Media. I believe what would be easiest is to just replace the existing reCaptcha module code with the Solve Media code.
Attached is the complete module for reCaptcha including the [url removed, login to view] file provided by Solve Media. If you're familiar with php and api then this should be a very simple project for you.
