As far as I know Theres no IM realm as yet, and as the gang from the Challenge is waiting for the possibility to make a leaderboard - ehich is impossible without armory-like thingie I doubt it wil happen. I have one Ironman at Hydraxian Waterlords - all of level 6 so far. This realm is my best sho, as some of the crew is there.
Somebody already reached level 60 long ago, so it is possible.
