Skype P2P is free, but when calling "real" phone numbers, then it cost money (from $0.021 per minute). So the real power of Skype is the P2P function which attracts people - just as napster, which was made by the same people. However getting paying users out of "freeloaders" ;-))) - well that looks like it happens 1 out 26... not sure how they make money of those 25 that does not pay - maybe they are just used as "bait" to get more people to signup. P2P have very low maintenance cost - the real cost is in acquisition, which is why the Ebay offer looks pricey.
