Is there a security/crypto expert out there who knows
if there's a way for a server to hand out a chunk of
executable code then, when the code runs and calls back,
it can verify the code is running unchanged (i.e. no
local storage on the client system at all)? I'm very
na=C3=AFve about security and my gut tells me no.

Some motherboards we bought recently were without
any reasonable places to put any non-rotating local
storage and ID/function to another machine would be a
pain.

The place where you want this (booting
a cluster) it's not really necessary as you can isolate
all the clients on their own physical net (he said
na=C3=AFvely, not knowing much about that either).
