Hi guys.
So I want to build and educational material site. I want to upload lectures, videos and setup live video chat for questions and answers.

I have few questions and i was hoping that you can help me figure out some answers.

1- I want to be able to setup a video chat room for all my students as well as private chat room to be able to talk 1 on 1. is there any plugin that does that or is it supported by buddypress.

2- I want to charge fee from students to be able to see content.
for example i want to make packages (limited & unlimited) for unlimited you get to use all features of the website: msges, chat rooms, video content. and for limited users i want them to use basic features.

I hope you can help me.
