Unfortunately this isn't reliable on OS X because prebinding can
modify binaries on the user's computer at relatively arbitrary times.

Thanks for the heads-up on this, Finlay. I have actually just
implemented self-checksumming on my framework as a means of countering
tampering (eg. users trying with a hex editor to edit serial number
blacklists embedded in the binary).
I had no idea that pre-binding could foil my plans... will have to go
and seek out some more info on it.
Cheers
Greg
