Distributing the Future 01 for 2006: "Emerging Telephony and Podjacking"

This week's show is brought to you by MAKE magazine--technology on your time.

:50 Voice Applications

I thought that voice applications were all about making cheap or free phone calls. Surj Patel sat down with me a few weeks ago in San Diego and set me straight. Surj is the co-chair of the upcoming Emerging Telephony (ETel) conference. He talked about a range of applications from a Babelfish translator for native Chinese speakers needing to communicate to English speakers to talking parking meters. ETel runs from January 24-26 near the San Francisco airport. (10:30)

11:20 Podjacking

There has been a lot of discussion within the podcasting community about a recent case of alleged podjacking. We have invited both sides of the podjacking story to provide audio explaining the situation from their perspective. I think there is an underlying difference of understanding of the technology and I begin with an explanation of what I mean. Erik Marcus explains that he feels an unauthorized RSS feed was published that allowed his audience to be stolen. You can read more in a pdj on podjacking that he has posted. George Lambert counters that he provided a service that Erik signed up for and that he did nothing other than what he promised. (12:10)
