DP, I'm trying to keep the scope of this FAQ limited to everything related to pilot licensing issues. You're welcome though to provide the definitive answer to those questions and put them somewhere. Maybe an "long distance touring operational issues" FAQ? Might want to include oxygen information as well (with help from IO540 and Bose-X), avgas/mogas/jet-a availability, VFR flying in different countries and so forth.
But otherwise we will need to include questions like "What's sternones opinion on aircraft type XXX? (where XXX is everything except Mooney)" too.
