S2Member and events

Hello! How can I combine S2Members and GeoDirectory to set up event showing/reading privileges? I know I can limit a user fron adding a listing removing the link through S2M and also I can restrict a user to post certain kind of listing on Geodirectory according to their listing privileges but what if I want a certain level of user being able to only post, view and edit his own events but not being able to see other users events, and I want other users to see all users events. And don’t want visitors at all being able to see certain kind of events at all. So I have 3 kinds of users:
1) unregistered visitors – cannot see certain event post types.
2) event posters – can post their own event but cannot see events from other users for the sane post type.
3) event viewers – can see everyones events but cannot create one.

Thanks,
Eduardo
