• Q: Circuit switching → packet switching → DTNs. What lessons can we take from our past experience and apply to a new paradigm of phones used for voice messaging? Email was replaced the phone. Is there a possibility of a voice spam with such technology?
• A: SMS is not a spam because it costs. The same could be assumed about proposed system.

• Allison: The system might prevail because younger people use more asynchronous communication.

• Comment: Peak demand for capacity might actually increase, because every one gathers in the same place to download their messages.

• Q: Why Grameen phone approach is not enough? How it is related to presented work?
• A: Grameen gives out phone to a lady in a village that accepts money for calls. This approach is not effective to penetrate rural areas where there is no direct coverage. Asynchronous communication would help here.

• Comment: IPhone visual voice mail demonstrates today that people actually like to deal with voice messages in this even in the developed world.
