Facebook Connect and Wall Post for Multi User Wordpress - NOT MULTISITE

I have a WPMUDEV plugin that allows for social connecting, login etc. It is designed to allow Actions to be posted to the Wall of a registered User but the way it is setup the only Wall that will be posted to is the owner of the main account of the site. I want each registered user to be able to post their Activity to the Facebook Wall via the Open Graph. Currently the process goes as such: USer registers with Facebook and gives permissions. User creates Post on the site Site posts message on MY Facebook Wall ** ** This needs to be the Facebook Wall of the USER not my wall, or the wall of the Admin of the site The plugin needs to be adjusted so that the correct permissions are requested and granted when the USER signs up, so that Actions can be autoposted to their facebook wall automatically. Experience with Facebook App integration to Wordpress essential. Please provide links to sites you have successfully integrated with Facebook posting permissions. Quote YELLOW in your response so I know you are serious.
