I don't know which program you are referring to.
One way is to set up your webcam with Skype. Then, configure it so that when you call your Skype account that it will automatically show the webcam, which is monitoring your home. Create another Skype account and call it. Since there is no official Skype program for the Palm, you can try using
EQO, which claims to work with Skype for the Palms like the Treo 650.
But that only works when you are "calling" your other Skype account and obviously data charges will apply.
