ESL classes via skype

“In this future, we have no need for interpersonal interactions. All such communication now takes place over Skype. Once a simple telephone replacement application, Skype now offers one or more parties to interact visually, using off-the-shelf webcams to create video phones that once cost thousands of dollars. Educators may collaborate by sharing slides and data with students.”
“Wait, what about ESL students?”
“What do you mean? They communicate the same way, via the audio/video interface in the Skype application. Distance education couldn’t be simpler!”
“What if they are afraid to speak? What if their culture demands they hide their face?”
