She is doing all that now. I think the program she was talking about was a GPS enabled thing where she can see where he is at any given time. If he says he is going to the gym - and this online GPS tracker which tracks using your GPS enabled cell phone - says he is NOT at the gym... she would know.
We have looked into these at work to use on our techs - the phones have to be the right kind of phone and then you would have to get into his phone (which he hides from you now and never parts with) to turn on the GPS to that it could be recognized.
I did this, and it worked extremely well. A $40 BoostMobile phone, pay-as-you-go, with all of its sounds disabled and a small piece of black electrical tape over its speaker just in case. Download a program from BoostMobile's website called Mapquest FindMe ($3.99/mo on Sprint/Nextel phones, and $1.50 daily on Boost). Charge up the phone, hide it in the trunk of his car, and -- voila! -- you can just log on to a secure website and track where he goes. You can even print out screenshots (great evidence).
You can also set it up to shoot you e-mail alerts if the phone gets within a predetermined # of yards of a predetermined location (I set mine up with our house, OM's house, their hookup house, her attorney's offices, and her place of employment). It worked reliably about 95% of the time. It was a pain, however, that you constantly have to re-charge the phone. Like DAILY. So every night, I'd have to retrieve it, charge it up, and then early in the morning get it back into the trunk of her car undetected.
It took her and OM over TWO MONTHS to figure out how it was I kept busting them! LOL OM was just soooo smart, he was SURE that it was the BMW Assist feature on my wife's car (nevermind that a 60-second search of the BMW website will tell you that they will NOT reveal the car's whereabouts to anyone who inquires, without a police report!). This little bit of intellectual "firepower" showed up on my voice-activated GPS recorder, which also sucked up batteries, but which was a treasure trove of good intel.
