In most Japanese language schools, "High Tech" means the students have mechanical pencils instead of wood ones. Which is probably not such a bad thing.
I have taught using a web cam, Yahoo IM and Skype. It depends on the connection. Make sure you get headphones and the students get them. I think its of interest to people working who don't want to come to school after work.
You can also use a Wiki to have a shared desktop so you or the teacher can write comments easily and the student can write back. It can be part of an interactive correction exercise maybe.
I have also made MP3 files for the student to listen to on their player while commuting and that can help them get value while out of the classroom. They can also tape their own voice if they are motivated about their pronunciation. Also, transcripts are good to have in both cases.
