I agree -- this is the easiest way to get around the limitations. I also 
went the El Cheapo way and used a mirror in my lightpipe tests (see pmap 
webpage). As I understand it, Anthony wants to simulate an actual 
prismatic panel which transmits and redirects light coming from the 
pipe. This is certainly more elegant (and realistic), but simply not 
doable with the current pmap implementation. Anthony will most likely 
have to go the awkward way with a separate transmitting (nonredirecting) 
panel followed by a mirror in order to circumvent the limitations of the 
system. Come to think of it, do you need a panel at all, then?
