Use of Portable Media Players on Library Computers

Someone recently asked if they could use public library computers to load songs onto their portable media player (ex. iPod). They wanted to download songs from the Web. They also had a CD that they wanted to add to their player.

Unfortunately, library public computers cannot be used to load songs onto a portable media player. Why?

We have two scenarios, but they are similar. One involves how to move files from the Web to a portable media player. The other involves how to move files from a CD to a portable media player.

A trip from the Web or CD into a portable media player MUST make a stop on the "non-portable" media player which resides on the computer (Our public computers use Windows Media Player 9). To remove possible security risks, we do not allow customers to save files onto our public computers. Therefore, this "stop" on a "non-portable" media player is not possible.

On top of the security risk, music files are very large files and I imagine our public computers would fill up rather quickly, not to mention the difficulty involved if a customer ever wanted to change or edit the music on their player. You would have to find the exact computer that you originally used and hope that no one altered your playlist.
