Non-USA Antares have had this facility from beginning.
All USA Antares, including yours, already have this capability.
I wrote and installed the facilities required for USA many years ago ;-)

Unfortunately its not so useful in practice.
Poor internet connectivity at many sites makes it dodgy.
Do you want a remote update over a poor connection killing the machine?
For this and other reasons, you always need a qualified tech on site for
updates, which makes this not so useful.

For diagnostics, better is diagnostic dump to USB.
USA Antares, including yours, have had this for years.
You may guess who wrote and installed it ;-)
