Regarding number 5, one company I worked for had the donut rule: if you left your computer unlocked, everyone was within their rights to send an email to the whole company offering to buy everybody donuts. It was expected that you would follow through (with whatever treats you deemed appropriate, didn't have to be sugary stuff). Of course this highlighted the security advantages of using a DVORAK layout on your keyboard and only sending email with Emacs which probably wasn't the intended effect, but every little helps.
