restrict number of posts

Hi Please could you advise if it is possible to use S2 to create memberships restricting users by the number of posts they can make whilst allowing full read access.
ie -
level 0 - can make up to 0 posts
level 1 10 posts
level2 100 posts - etc.
If this is possible, please could you offer some pointers for configuration.
Thanks you
