I don't know anything about cksum(1).
(Welp, I didn't untill after starting this message. This is
 version 2 :)

But I just did a cksum(1) on a file.. Why can't that be directed
to a txt file per directory by the powers that be at FreeBSD
head quarters, Then someone (me if needed) could whip up a simple
Dos & Unix based program to read it and verfiy each file.

-Enjoy
