.JP Registry: DNAME aliasing for idn.idn?

I read this May 4, 2008 release from the Japan Registry Services entitles "DNAME Issues Regarding IDN TLD
Implementation".

For much of the last year only the term "aliasing" has been used by ICANN staffers, Tina Dam in particulary for the possiblity of converting idn.com, idn.net, idn.jp, idn.tv etc to also alias as idn.idn (equivalents).

Can someone from ICANN shed some light on what is going on with DNAME (solution proposed by Verisign), and also with the options for alising of .com etc. into the new idn.idn space.

Now that testing is done, and idn.idn are cueing up for major language releases in the forseeable future, are the various registrars... JPSR, CNNIC, Verisign etc. now open to begin to alias their gTLDs and ccTLDs into .idn should they choose to do so?
