Managing Mobile Technologies

We are purchasing iPod Touches for student use. I am looking for examples of school policies for management of these devices. At this point, we are planning to check them out through our library. Does anyone have ideas for how to handle lost or stolen ones? I assume we need to draft some sort of parent letter/parent policy? Currently, mobile devices are not allowed in our schools although our district is rewriting the policy. I don't know what the district's policy will say although we doubt that it is going to address the use of district owned mobile devices.
