I have done the exact opposite but both sides of the border are under the same jurisdiction. How would this work for a summit on the GI/EI border (not sure if there is one but if so it presents a problem to us, Rod & Vicki)?
Under these proposals does the AZ extend into both countries as before, so activation can be done by low level licensees each on their own side of the border? eg activating an EI summit with an MI6 callsign?
(If my EI/GI example is invalid there are plenty of real examples in continental Europe for which the same problem might apply.)
Sorry if this is unclear - English may be my native language but I am not always very good at it
