Boot time

OK, suppose I have a thousand diskless hosts connected to this Intrepid M thing. How long does it take to boot all thousand machines? Unless Levanta is doing something remarkably clever, I'm betting it will take a remarkably long time. Local disks all operate in parallel, but the Intrepid M's network interface doesn't. Even if all the hosts boot from (mostly) the same set of files, and they're all buffered in RAM, the files have to be sent out a thousand times each -- unless it's using some sort of broadcast scheme. I'm betting it's not.

If you use this system, you'd better have arrangements to avoid a need to boot all lots of hosts at once, in a hurry.
