IFC is clearly gaining a momentum in the AEC industry as an open standard software neutral file format so having IFC export from Rhino is clearly a big advantage for companies who use Rhino/Grasshopper for early design/analysis and want to integrate that data into documentation phase into a tool such as Revit. Lately from what I have seen and experimenting with IFC, I am becoming a big fan of IFC for data exchange between 3D/BIM tools.
From UK government BIM maturity level model point of view, IFC is clearly going to be part of integrated BIM at Level 3 and hence will have bigger role in BIM output/deliverables.
