Hi Patrik,

Unfortunately, I am not as technically knowledgable as you are so I
rather not comment on what you have wrote.  However, what I am certain
is that you have illustrated the fact that
applications/clients/users/servers/etc can be made to take advantage
of this explicit labeling of what "script" an IDN is in and over time
(with people writing appropriate applications) can be developed into a
very powerful and useful system.  (Unlike TLD such as ".gov", ".ca"
which serves next to no purpose from an IDN's perspective.)

Thanks,
Ben
