Why would it be laggy? We'd only be sending simple information - most of the time it would be purely textual. It's not like lag would do any harm anyway - we're not talking about any real-time, time-sensitive stuff here. The teacher draws a picture, the students look at it. Even if lag delays the reception by as much as five seconds, does that prevent the student from seeing the diagram? Does it stop him/her learning from it?
