Online Traning / Classroom Script

Ok,
Does anyone know of a script that can be used for Online Training / Classroom?

In short,

I want to give clients access to online classes,
where they can download the needed material for each class and watch either pre-recorded videos or live streamed videos which they can then discuss in a chat at the same time.

 

i think there is not such script available though you need to get a custom solution.
