	I looked over your script. I plan on doing some trial runs with it. I
think the trick where you re-run the sync and then boot the user off the
connection should work pretty well. I hadn't totally fleshed out the
scripting on the conversion since there is a lot more I need to do with
the database and configuration files first. It appears I can use your
script as a starting point for our configuration.
