Depends. How do they handle it now? Ham signals don't stop at the border.

Generally speaking, the transmission needs to follow the appropriate
rules in the country of origin.

Why? The TNC could be transmitting the ham callsign in morse tones every
9.5 minutes; that form of ID would never be picked up by listening TNCs
or the APRS infrastructure, yet it would still be perfectly legal
according to the FCC rules. There is no requirement that the ID must be
in the From: field of the APRS packet.
