[Casper] leopard migration

[Chad Brewer]

2 XServe Xeons.  1 to run netboot and serve as the AFP file share.  The
other just runs the Jamf database and tomcat.  I would guess that unicast
works fairly well for up to around 10 sessions (more if you don't mind
waiting a while).  The problem with this is that when your doing all of
these at once, every session is trying to use 1Gb of bandwidth.  10
computers takes you down to 100M per computer.
