Ultimate Facebook Plugin with PaidMembershipPro? Will it work together?

Hi,
We have a membership site using PaidMembershipPro.
I am intrested if anybody know if the WPMUdev Ultimate Facebook Plugin will work with PaidMembershipPro.
I see you can login to the site using your facebook id, will this mean they can sign up as a paid member using their face book ID??

Many thanks
Andrew
