Reward members with choice of free product

Hi guys and gals -

I have been banging my head on this one and am looking for some assistance and/or ideas on how to pull this off.

I am looking to create a membership site using Wordpress wishlist member. It will be a DVD club where members, depending on membership level will get the opportunity to get a free movie (or 2 or 3) depending on their membership level - only from a particular category, like new releases.

I would like to create group permissions where if a member (customer) is in a certain ZC group they would be entitled to their free movies within a certain category only.

The groups could have customers manually added, I suppose, but a bridge with a user level would be better.

I know I can't do the subscription part through ZC, any ideas on how to set up this kind of pricing matrix (free movies inside a category)? And any ideas how to alert ZC of member's status (active or inactive) depending on their subscription renewal?

Hope that this makes any sense...

Thanks in advance!
