exoops weblinks module modification

I need to modify the weblinks module for exoops. I need to add a Reciprocal link exchange instead of just a link post.I will need to make sure that the user is a member of the site, that our link is on the page that the member put it on and that his link is a valid link. It will need the option to check for the links in the admin. Send out email if they dont have our link back. I have ReciprocalManager script in php if you need a model to base it from. I would also like to include some search results from search engines based on the catagory name.
