"In a final product," Peter said, "we'll of course build-in a microphone for hand's free operation." He hit a few keys. "Now, say you are driving in your car and you remember that you need to send an e-mail or fax to an associate to confirm an upcoming appointment."

"Okay," William said. "How do I start."

"Do what comes naturally."

William thought about this for a second then spoke into the microphone. "Pip, create an e-mail."

The Joey's hard disk was busy for an instant and then a blank e-mail form popped up on the screen. The Joey said, "To whom?"

William turned to Byron with wide eyes. Byron nodded and whispered, "Go on, give the little fella what he's asking for."

William said: "Peter."

Joey: "Peter Jones? Or Peter Smith?"

"Peter Jones," William said, then he covered the microphone and was about to say something, but Peter anticipated his question before he could ask it.

"That's the agent at work, behind the scenes. It found two Peters in the address book and didn't know which one you wanted, so it asked you to decide."
