If all EU-based readers can wind their clocks back, I spotted this article on Australia's Solvency II cousin which seems to have all the hallmarks of the EU/IAIS experience.
I was very interested to read that capital requirements would be substantially higher - sadly I'm no expert on calibration, but this shows there is an intense lobbying effort ready to go. This may even mirror the history of the QIS exercises in Solvency II, where the calibrators have started on the conservative side and folded when necessary.
