In the past years, I've seen a couple of cluster installations with _a lot_
of computers, ... so the scenario is really valid (though it's something
that you might not use at home ;-) )

Well, network booting is not always a straight forward job, so there will
certainly be a a little bit of complexity in these settings, no matter
which way you do it. But the current version of the draft has been
discussed with the folks from the UEFI forum already, and there are
certainly a lot of client firmware implementors there, so I think the
current version can't be that wrong...

No offense! Sorry if I expressed that wrong ... as you might have noticed,
English is not my native language... of course I meant to say, that nobody
complained until the point in time right before Damien did.>
