So, after the reprojection and then importing into CAVE, it seems to be 
displaying properly?

Prior to the reprojection did the saved shape output have a .prj file?  I'm 
wondering if maybe there was no 
projection information originally, and Arc is able to assume a default which 
works, but CAVE wasn't able to
make that same assumption.  And after you did the reprojection, now it was 
explicitly stated in the shape file
data?

Does my assumption make sense?

To my understanding CAVE should be able to handle many different projection 
types, but I believe it needs to 
be specified, I don't think it can make a default assumption.  Do you know what 
the original projection was?

Thanks.
