Facebook Login / Post to Facebook or Twitter for affiliates from within WP Affiliates

Hi...we are looking at WP Affiliates for an affiliate / referral program.

Most affiliates will be posting their links or ads to facebook or twitter and we are looking for some integration of facebook and twitter for affiliates, so when they get their banner / code, they can simply POST TO FACEBOOK or TWITTER right there...making it easier to post the banner or link to their facebook or twitter. The idea being that upon login, the text from the affiliate link code would quickly create a post for the affiliate on their facebook / twitter.

Is this something custom you would do at a cost or would it be a custom project to post? Any idea on how difficult?

Thank you!
