<p>mdcisp: IChat is a program for Macintosh computers. You have to have a camera in the computer (or connected to the computer) and the person in the other end (ie your kid at USC) has to have a camera. You can connect using AIM messenger. You can also “chat” without the camera… but you will not be able to see each other, it will just be instant messages.
I understand there is also a way to do it using a PC. I do not know how yet.
My 16 year old son showed me how to do all this, because I had no idea 
There is NO CHARGE for this service…as long as you have internet connexion you are set.</p>
