Hi vitrinedtv, I believe that MediaSignage are reworking their API as of the V4.x release - though speaking with Live Chat I've not been able to establish any timeframe for this. Hopefully though this should open the door for developers to build custom integrations with their own apps etc.
I wait as you do for an announcement/documentation etc. to see what can be achieved with the new API. Should be exciting for devs and Enterprise customers.
