Alternatively, if Skype wouldn't be realistic for my time frame, is there another common way to video chat that would have been available?
ETA: Great answers, thank you all! I realize from some of the answers that I should have added a couple more details to the question. My character is in the US, talking with someone in the US. Having video is the important element - - he needs to be able to see things on the other end.
THANKS everybody. This is all very helpful!
