History of WO deployment on OS X

I've recently been adding major updates to the WebObjects entry on  
wikipedia and am confused as to the history of WO deployment on Mac  
OS X... hope some of you with long memories can answer these  
questions and i'll get the entry re-written...

(1) I think I'm correct in saying that WebObjects deployment software  
has come bundled with Mac OS X Server since it's initial 10.0 release  
in 2001.  However did this come with an unlimited WO license key? (or  
did you have to purchase WO itself to get this?)

(2) Much excitement greeted the release of Xserve in 2002 because it  
came with WO deployment... but was this really that significant given  
that it was already part of OS X Server already?  Could it be perhaps  
that there was a deployment license with this?

(3) What was the significance of Panther Server... did it come with  
some nice server admin tool front-end for WO or something?

(4) Is it only with the release of Tiger than OS X Server's come with  
BOTH the deployment software and a license key?

Many thanks
