Did you manage to conduct experiments with NetBoot?
I've been doing this for a while and tried my luck on all server versions, starting with OS X Server Rhapsody 1.0 on Beige G3 and ending with Mac OS X Server 10.5 on G5 DualCore. The NetBoot package for OS X Server Rhapsody 1.0 contains Mac OS 8.5.1 and it boots perfectly over the network on the G3 BW that I have.
OS X Server 10.0 - 10.2 looked strange, in some moments it was not even immediately clear how to configure it, because with each version everything changed rapidly.
I plan to publish my experiments on the blog as soon as I win over laziness.
