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 ---- It certainly allows sloppy/generous/obtuse internal delegations. Some may say that saves time/management headache/whatever. MY question is -- How do you know if a justification for _public_ space handling a large NAT'd pool is the proper size and not an over/under allocation based on the customer in question?
