Joe passed this along earlier to me and it shows a proof of concept (free beta available) that allows you to take an IFC file and import the geometry and data (ex. Revit parameter information) into SketchUp. This plug-in (available here) was created by Secom and distributed by Cadalog, Inc.
Sounds interesting for the small niche of folks who need to go this direction (BIM to SKP) and I am in the process of downloading now to test with. More later...

Update 1
There are two sample files you can download to work with from the site above:
- SmallerBuildingIFC2x3.ifc - 558kb file created with ArchiCAD 10.00 release 1 using IFC2x3 schema
- TOFU2.0_2x3_simplefied.ifc - 1.22mb created with ArchiCAD 11.00 release 1 using IFC2x3 schema
There seems to be overlapping geometry (not reversed faces) in many spots but the entire model comes in as groups (for the objects).
