You've got to be kidding. Do you think it's clear to the average consumer buying a GPRS phone what NAT is, and why they might or might not want it? Do you think the use of NAT will be explained to these customers? Or clearly stated in 5pt text on page 17 of the service agreement? IMHO, as one of the people who will likely be using Cingular's GPRS network with a Danger HipTop, I _strongly_ hope they choose to use routable address space instead of NAT. I would hate for NAT to be an impediment to some cool new app no one has thought of yet because these gizmos aren't in widespread use yet. >This is not to say that if, as Eliot posits, the next Big Thing on the market >requires public IPs that your customer base won't all jump ship. That's a >risk that providers will have to weigh against the benefits of NAT. I'm more concerned that if the major metropolitan markets deploying GPRS all use NAT, then the Next Big Thing won't ever happen on GPRS devices. Customers won't jump ship if they have no where to jump to. That might sound attractive to the bean counters, but think of the customers you might never get in the first place. Also, I don't see how deploying NAT could be a cost savings over requesting real IP space. -pmb -- Ring around the Internet, | Peter Bierman <email@example.com> Packet with a bit not set | http://www.sfgoth.com/pmb/ SYN ACK SYN ACK, |"Nobody realizes that some people expend We all go down. -A.
