I lived in Mexico a long time ago and recently got back in contact with a friend from there over Skype. We've chatted a few times using video chat in Skype and it was a really good way to get back into practicing Spanish. I think it you were going to do this on a bigger scale you'd need to have specific lesson plans and conversation topics as well as tips for both the native and learning speakers. For example, tell learner how to ask how to properly phrase a sentence. Another idea is to have the people on both ends learning each other's language, so rather than teacher-student, both are students, one learning Spanish and the other learning English, for example.
