Membership: The Return of the Multiple Subscription Levels

(I posted this as part of another topic but it was marked resolved so I wasn't sure if it would show up yet.) I am a new user (thanks for the welcome) and am wondering if the multiple subscription form idea is in beta2 - I can't find it yet if it is.

Basically what I want to do as part of the pre-launch phase is give a lower price subscription to certain close friends, and once they have subscribed I want to give them a different subscription form/code with a slightly higher price (but still discounted) they can offer to their friends. So I need to be able to offer either invite codes tied to different pricing tiers, or different subscription forms. Or, what's the work around?
