The problem for the iPod Touch units is that it remembers the students' username and password, which is undesirable. Yes, I know there's the "Forget This Network" button but realistically we cannot expect students to remember to press this button every time they log on using one of these.
I have looked at the iPhone Configuration Utility provided by Apple for enterprise-type provisioning of iPhones and iPod Touches but can find no way to prevent the caching of passwords.
We have an Apple AirPort that could be used to bridge to the campus Ethernet (which requires no logon). This is already being done with some other equipment including MacBook Pros. I've e-mailed my boss the suggestion, but as it stands now we (i.e. me) have to figure out some way to solve the credential caching problem.
Any clues, Apple furries?
