Blender and VR - possible?

General question: A colleague who is into VR and data modeling has asked if Blender or the Blender Games engine can be used for VR data displays - he uses geological information and GIS information. Are there any plugs available for this (eg: shapefile)?

Is anyone working in this area who might be able to provide information or general pointers on a starting point.

TIA.
