Yes that is the script.  I think it was writen for Python 2.3 but it does work reasonably will with v2.4.  It did crash Blender though if I Closed (Exit can't recall the exact name of the button), so I just leave it running in the background.  I also still have to edit the exported oject file to change the o's for objects to g's and varify the names are right ( it tends to add the material group name to theobject name).  To be completely honest I haven't even tried Blenders new Import/Export function to see if  it would work with the right settings.
