Looks like we have the first report of a honest Flyertalker disclosing his travel to Iran to a US consulate in a VWP country in the Destinations>USA forum, and it apparently didn't go so well. It's not clear from the post how much travel to Iran contributed to the conoff's decision - insufficient ties to Norway were cited by the officer - but the fact that s/he was questioned extensively about the Iran trip in Oslo suggests that at least some US officials are seeing Iran's inclusion in HR 158 as something more serious than election-year political signaling.
