Provide PXE (dhcp, dns, tftp) on an unauthenticated VLAN.  Your original 
email suggested that you'd want users to auth before a system would 
boot, but that's probably not possible.  If you want to authenticate 
users via username and password using RADIUS, then there has to be an OS 
running to provide an interface in which they provide credentials.  It's 
not really clear how else you'd imagine that working.

Well, I guess I'm confused because having explained where you'd find the 
interface in which users will provide their RADIUS username and 
password, you think this process is unfeasible.  Perhaps you could 
explain what you're looking for, more precisely?

OK.  I'm not sure how your opinion of GNOME is really relevant.  I'm 
describing it because it's an example that's probably within reach for 
both you and me, given that you and I are communicating via a GNU/Linux 
focused mailing list.

I'm sorry my voluntary attempt to help you out wasn't to your liking.
