I've already been in contact with both Nicholas and Colin about running intro-sessions of RMU at GenCon 2013. Six sessions, 4 hours long w/first hour being an intro to the system for people not familiar with it, then up to three hours of characters trying to complete a misison. Have a points system defined such that I can provide a score based on how well and fast they complete the mission. Colin is going to supply me with some prizes for the members of the winning session. All six sessions filled within 24 hours, so there is obviously demand for Rolemaster sessions at GenCon.
So as encouragement, anyone else who might be interested, be sure to contact Colin to let him know. ICE/GCP is very willing to work with people to help support such activities.
