[LAU] Remote mixers - open APIs

I am part of a community effort to buy a PA for band use. Being 2018 we will want remote mixing.  (Where a network take the place of a snake). I am nervous about buying gear that Apple or Microsoft will deprecate.  Is there any body making remote mixers with open APIs that if they are abandoned by our corporate overlords  will still be useful?  Any experience building alternative controllers for remote mixers?
