Looking for a program

[imnuts]

I'm looking for a program that someone linked to in a thread here but I don't remember what it was called or which thread it is in, so I'm hoping someone knows what it is. The program is something that runs in the background and will receive coded text messages and respond with the current GPS location of the phone. It's mean to be a security app and can respond to requests via email, text, and ftp. I've tried searching the forums as well as just online and can't find it, so hopefully someone knows what it is and can help me out. Thanks.
