Rant to follow...

I've got a simple solution to help all the manufacturers "get it". Don't buy or spec any product that doesn't have discrete codes and make sure to let the manufacturers know every chance you get.

With all the good things that CEDIA has done, I consider this it's largest failure. The fact that after all these years CEDIA has not put together a simple set of protocols for all the manufacturers to follow is insane. CEDIA could have used their clout to solve this issue years ago.
