That would identify the originator of the packet, not the transmitter,
so it doesn't solve the regulatory station ID requirement. Assuming of
course that you don't want to rewrite every packet at every node.

I don't think anything fancy is required here, legally. Just put the
callsign into a UDP packet addressed to nowhere and transmit that as
required (every ten minutes when the transmitter is active).

We have to be careful to pick ones that never encrypt the payload, in
order to be legal in the United States. Even then, we will probably be
illegal in most other places if we use any cryptography, even for
authentication.
