For the record, rJava and JRI work fine with Sun's Java 1.6 on 64-bit  
systems (fine being defined by the fact that JGR works :)). JGC-based  
JRE is still quite buggy on both 32 and 64-bit machines as far as we  
can tell, but for non-GUI task it seems to work. However, I don't  
think this is what Brian has in mind ...
