smart scouter will send pictures to your cell or email. I would need a sat phone for it to work in the places I've been scouting, I don't know that their Sprint plans would do the trick. But yeah, the cams are like $650 plus you have to pay for data transmission.
Then there's PixController trail cams. They're $350 plus you have to use a Palm Treo phone (and it looks like the unit is just a fancy motion sensor setup that triggers the camera on the phone)... plus the cellular plan, plus a data plan (the files are too big to just send as text messages, I believe) plus you'll probably want the external battery pack because cell phones don't last very long if they're on all the time.
Those are the two I've heard about.
