I've written a simulator for this (though it matches 32 bits, which is
the same as you compare for normal blocks).

PGP is all about proving that I'm the king (if I say I'm the king and
issue, say, an order to execute someone).
PGP will not prove that I'm not the king and only a lowly peasant. This
problem cannot, to my knowledge, be solved by cryptography except by
only issuing one key to one person, and ensuring that you do that is
the original problem you're trying to solve.

If you haven't caught on already, I hacked the core. I don't do RC5
either. I stopped bothering a long time ago.
Note that I'm not sure what those flushes in september are, since I
don't remember doing RC5... Hm.
