I agree. Like i said, i will only do this upon request of EMPB.
I will await the outcome of the alternative approaches.


I still cannot understand why they just didn't choose SIPP with
NSAP addresses. It seems like such a waste of effort if we have
to create new address structures, addressing authorities,
application forms, databases, address encapsulation standards etc. 
Why not add 4 octets and use NSAPs. It is so marginal a change. 

Sigh.....
