Boy, if only these guys had "user-created" somewhere in their mission statement. It’s already a Web 2.0 smorgasbord. If I understand it correctly, the idea is that you and your friends all sign up and register your phones with the site. Then, when you want to call someone in jolly old England or jolly old Moscow, Jaxtr acts as a middle man, calling you both from local numbers where you are and running your conversation through their servers. Sounds pretty sweet.
To be honest I’m not much of a phone-talker, but it would be nice to talk to my brother in India on my regular phone instead of worrying about whether my neighbor is going to shut off her Wi-Fi randomly like she always does.
