Dear Team,
we have switched from Apple Remote Desktop and Jump Desktop in spring. Overall, we are happy, but we miss some features from ARD.
I do not know if a 3rd party vendor can implement those but it would be very handy if we could send UNIX commands to selected devices (all at once ideally).
Another nice feature in ARD is the ability to install pkg-files…
Perhaps you see a chance to implement it now that the code is “in your hands” 
Best regards,
Christian
