There are checksum programs around. Don't know what the implementation is.
In any case, it isn't too hard to code a trivial one for this purpose. In
fact, when I get the time (and when Bob comes back from holiday) we can do
most of the checking just on the Mac end since tar-ing and then detar-ing
seems sufficient to trash some files (ie no file transfer necessary). I'll
keep you posted.
