Semirelated. Anytime I have written a protocol with a checksum I implement a 'magic checksum' that just passes. And a debug mode that enables it and diagnostics. The reason is usually if somethings wrong with a packet of data the best thing to do is ignore it completely. But that makes development insane. So having two modes gives you the best of both worlds.
