Good news: I could not find, nor did I hear of, any record of anyone being violated for flying under section 9.
Bad news: Because nobody's been violated, there are *very* few lawyers with section 9 RVSM experience. Lawyers get good experience from defending clients.
I did find a lawyer with some experience, gave him what I had, and paid him to write an opinion letter. The last line of the letter reads "Based on the information you have provided, it is my opinion that your aircraft and operations in RVSM airspace are compliant with section 9."
I'm stopping this quest right here. When I asked him about getting a letter from the local FSDO, he said "Why would you poke a sleeping bear?"
