Both great answers - thank you Sean and Brighton College.
This just confirms my suspicion that it's not a good idea. You know that sickening feeling you get in your stomach when something doesn't feel right? That's the feeling I got when approached from our customer about doing this. I think that gut instinct as Sean alludes to has a lot of truth in SEO.
I agree with both of you on "it's better to have a few good outbound links" and "the more inbound quality links vs outbound, the better."
Thank you!
