Note:  Found this little update on Todd Pinkerton's blog about some of the projects he has come across at the conference.

"this week I’m in San Francisco at the O’reilly Emerging Telephony conference, chaired by my good friend Surj Patel. The conference is all about how the old-school world of telephones and phone networks are now merging with the Internet. So now, anyone who can write a web application can create a voice service.  This is part of the inspiration behind Ringfo."
