Is this tkemc in addition to or instead of a user interface
at the machine?  What if someone at the desk starts the
machine after a user at the machine stopped it for a tool
change?  I assume there is a way for the local operator
to prevent remote starts.

I hope he has an e-stop button in his kitchen, and that
his machine is located in an area where kids, cats, etc,
can't walk up to it while he is 100' away.

I wasn't aware of that level of flexibility.  Very cool,
as long as the safety aspects have been addressed.
