I understand that the added information might be useful, by why stop there? Why not have a deck hand check everybody's computer after they board and be sure they stayed within the rules, and while we're at it, make sure that everyone has 12oz of water before each dive and is properly hydrated. Oh!, and....

One of the things that attracted me to diving years ago was the culture. The prevailing attitude was "we're adults, who having taken the responsibility of learning how to manage the risks of our sport, can take care of ourselves". It's the perfect marriage of freedom and responsibility.
Lately people keep coming up with things others can do to make us safer. We keep moving farther from the original premise of "caveat diver" muddling the lines of ultimate responsibility - "I thought you were checking that" - and thereby increasing, rather than reducing risk.
If you look at the financial mess the USA is in, is there anybody who doesn't wonder if the assumption that regulators were watching, raters were rating, and insurers were insuring, led folks to make poor decisions figuring it had to be OK. Don't you think that if folks didn't put their trust in others and did their own due diligence many of todays problems wouldn't exist?
Maybe the best thing a dive boat can do is mount a mirror at face height with a sign "person in charge of your safety".
