Hi Darren,
It will be PXE based. I have the netbooting working as a bench top demo.
It is just trying to figure out how to make something more like a 50Mb
image than a 2Gb image. 20 or more machines booting 2Gb across the
network isnt going to work ;0) Especially when the diskless clients may
only have 512mb of ram ;)
