Hi Folks, 

In line with Isaac's question, see attached, what are the addressing
consequences or issues for a PRMD user associated with an ADMD that 
spans international boundaries? In other words, a PRMD connected to a
supra-ADMD? 

Should we seek to recognize a reserved Country Code like 
PrintableString "XX" and NumbericString "000" and seek to set 
up an international registry for those ADMDs wishing to operate as 
a supra-ADMD. 

Would an ADMD serving PRMDs in other countries, but not offering 
subscriber services to residents in that country, as suggested 
in Isaac's message, be considered a supra-ADMD?  What are the 
international law, billing, currency and settlement issues surrounding 
such a venture? 

Should this discussion and ultimate solution, if there is one that
can be agreed, find its way into the CCITT/ISO standards arena as 
a US contribution?  Should the ITU be approached to set up such a service?

How much unlike is this from the interworking and addressing issues 
created by a supra-PRMDs?
