It has always been my understanding that while the rules are strict, google does not enforce them the same way - since there are quite a few legitimate reasons to "cloak", for example non-text-content. I don't remember which major site it was, but they were serving audio-recordings of shows to their users while serving transscripts of said shows to google. makes perfect sense from every angle.
plus, in my personal opinion, as long as google is not willing to support something similar to yahoo's robots-nocontent-attempt, it might be even in googles interest to have the webmaster decide what to show - you don't need your navigation indexed on every single page, esp. if you're using google's sitemaps program.
