That's correct.  Part 97 regulates the type and emissions of radio links, 
but not the type of non-radio control.  Nor do I see anything within Part 97 
that addresses "positive control" of the link to ensure that the transmitter 
is under continuous control.

In several non-Part 97 systems (e.g., Part 73 - Broadcasting), the FCC 
generally requires a watch-dog timer device of some kind to inhibit 
transmissions when the control link is lost.

It would seem reasonable, albeit not a strict FCC requirement, to utilize a 
TCP/IP polling method to inhibit Part 97 transmissions.  If the transceiver 
receives no polling command within a pre-determined period of time, the 
transmitter becomes inhibited from further transmissions until control is 
re-established.

For example, let's say you initiate the "TUNE" function on your tranceiver 
from your remote location and at that moment, your link to the ISP vanishes. 
You now have a transmitter operating completely out of control.  And 
although Part 97 may not specifically address Internet-based remote control 
systems, you then become under attack from other areas within Part 97.

It would certainly make sense to include a similar timing device in the Omni 
VII.  I presume some additional coding would be necessary, but without any 
further refinement in hardware.
