you can spoof the number using telco access to gateway (access number masking), but if the system also uses an access number also then it wont be possible. That's why it would be wise to use an access number from a CP, other than that you'll only have to worry about denial of service which would prevent any SMS to be sent/received at all but that can only be done on a limited area using scramblers, but that would easily be detected so i think no one would go as far as doing that except.. the govt? T_T
anybody with a 1000$ fpga and a modified adsl modem can do that. but of course you can be caught very easily since you are affectively announcing where you are.
As for tracking users, you can opt to use telco's location base system (LBS) which is precise to about 500 - 1km depending on the location (buildings, weather, etc.) but using it on real time is limited due to the high amount of resource it uses.
