Hmm, I have not investigated this much, but I wonder if Pawel's
(talented author of Geom Gate!) Cerb framework can be used for
executable checksumming; since the framework can intercept
system calls, it is probably possible to look into exec() and
friend's arguments, and then use that for checksumming
somehow... hmm, it's just an idea that crossed my mind...
FWIW, I was once working on this Binary checksumming stuff, but
then lost interested in it for whatever reasons (further
education etc...). One of the things that I was kind of not
keen about is how demand paging is thrown out of the window with
this code. I am not saying I am against it or anything... ;-)
