Here's how it works:

First of all, you need DSL or cable modem high speed internet service.
Dial up will not work.

You need a computer video camera mounted above your screen.
Or, a digital video camera (with firewire) mounted on a tripod. This
is best.

You will need IChat AV for Mac, or AIM (AOL Instant Messenger for PC).
You can download these from Apple.com or AOL.com

Ineen (http://ineen.com/) works on Mac and PC
IChat AV on the mac can exchange video with the latest version of AIM for windows http://www.aim.com/
Just shoot me an email for payment details, and how to get started

This method has been a very effective teaching tool. Students as
far away as Europe are able to learn bass, join bands, play out, make
money, funk out, have fun, and so on.
