I'm going to try to find a little time tonight to knock the handshake thing up in a CLR routine - it's a lot easier to write the m-from-n requirement there, and the processor-intensive nature of the task should make it suitable. It's probably going to be of no use to the Ninja - but I keep wondering about it 😉
