Cell backup alternatives and AMPS sunset clause?

An email went around sent by the nbfaa (nat'l burg + fire alarm assoc) a few weeks ago about AMPS and cell backup options (see part of it below). just wondering what non-AMPS solutions are out there... i know of two -- aes intellinet

- invest $20k or so up front in a local network that you operate, no recurring service costs to a third party, just the cost of running the network yourself) and alarm.com - does wireless backup and web control/reporting through a non-AMPS wireless connection, no upfront network buildout costs but recurring monthly service fee to alarm.com).

does anyone know of other wireless options that aren't threatened by the AMPS sunset clause? is honeywell coming out with anything to replace Alarmnet C? or telular?

from Jan 5th 2006 NBFAA email: "The Federal Communications Commission (FCC) has established a sunset date of Feb.18, 2008, for the requirement that cellular carriers provide AMPS service. This sunset date is significant for you and could have an adverse impact on the thousands of alarm customers that have analog cellular (800 MHz) communicators installed in their homes or businesses for the purpose of relaying alarm signals. This includes Honeywell's AlarmNet C, Telular, Uplink, DSC's Sky Route, Numerex and similar cellular-based products."
