We are family, (I got all my sisters with me...)

As the telco market gets more and more crowded, and the mechanisms to attract customers become more and more cutthroat, it's worth the telcos considering a more loose definition of family and friends.
I reckon it's about time telcos started making on-net voice calls free. I can't think of a better way to get a group of customers onto your network, providing their information and giving you a good shot at the money they do spend on communication services. Telcos already do this for big customers (based on incoming call revenue share), now we're all family, right?!
How do you think your Auntie Julie got on Skype? Sure, viral marketing, but did she sign up because it gave her cheap calls to Ecuador? No, it was because her son/daughter wanted to call her for free...
