Security of data

[Mike Davis]

If you allow users to access something on their computers you must
operate under the assumption that you have just given that user the
ability to keep any information they download.  If you really want to
prevent them from removing images, make them use a kiosk or something
to access your mapserver information.

As far as I know every system that purports to limit user access to
information "temporarily" downloaded to their computers (quicktime
temp files, flash audio, etc...) has been hacked.
