>While the protocol is open, the CODEC is not. 
  
Just for the sake of discussion, is there a P25 hardware codec available for
free?  (since P25 is an open non-proprietary protocol by definition)

And...

Is there any thing about the JARL Dstar protocol that prevents someone from
developing their own CODEC solution?
