Yes, you got the point. The problem, unfortunately, is right there: source code. I'm not very familiar with it, and Madwifi code is very difficult (at least for me) and so I was looking for someone with great experience, or someone who did something similar to what is my actual task. Anyway, thanks for your comment, I appreciated it.
