unified registration for all subdomains

Hello,

I have gone through the plugin very well. I really liked the way it is working, but what I need is some modification on the service for which I am ready to pay.

Actually I have build several wordpress sites which are in different sub-domains, and I have customised the CMS a lot. I have customised the system the way so that it works as a unified Registration/Login. It means if you register in any one of the sub-domain then you are actually getting registerde in all other subdomains with the same credentials. Now when you login from any one subdomain then you are actually logged in throughout all the subdomains. Now if a normal Viewer/User use you plugin to comment in any post of any site/subdomain then your plugin is actually creating a new user with the credential he/she used for any login say with “facebook”. Now what I need is when your system is creating the news user for that particular site/subdomain can you create the same user with the same credentials in other sub-domains too? so that the unified registrations concept stands here. We will use the same “application key & secret” throughout all the sub-domains, please help me out as I am really looking for your support…

Thanks
