   I'll probably have to get a couple to play with.  The nonpolarizing thing and   
   the asymmetry make them potentially harder to use than PBSes for anything at   
   all fancy--for instance if the phase shift between p and s is more than a   
   degree or two, the output    
   polarization will be a mess.
