I like the NDI capability and have a suggestion.  It would be great to be able to use NDI as an input - be able to display/project an input from a network device such as sharing the screen of a computer, tablet, or even a phone.  Example:  this last Sunday we were introducing "Church Connect" - a feature of ChnurchTrac.  It would have been really effective to have been able to demonstrate how to activate and utilize Church Connect using my phone and displaying the phone's screen for the congregation to watch, step by step.
