[Casper] leopard migration

[Chad Brewer]

I have a similar project planned for the summer.  I have already
determined that Casper's unicast imaging is not going to work very well
for us.  I am planning on using multicast ASR to deploy the image.

Basically, I have taken my casper image and run "asr -imagescan" on it. 
Then I am dropping Casper's FirstRun script into it to take care of the
JAMF client service.  I haven't tested this in mass, but it seems like its
going to work fine.  I'm open other ideas, but we've had problems doing 10
computers at a time with unicast imaging.  I want to be able to do 50 to
100.
