Reverse Logic for membership and Pro sites

Hi folks sorry for the many rapid fire questions today, just trying to sort out the model for new users before i start the final process pf activating everything and sending the site live.

Ok having i think finally got my head round the problems with integration between the two, i had a thought.

Would it be possible to set membership up as a plugin under prosites for a user to control access to video conferencing to do online lessons etc, or to restrict content on his pages to certain groups of users (create classroom material for them or test pages etc.)

Could they offer this material as free and or premium content their students could pay them for?
