[idn] call for comments for REORDERING

["Soobok Lee" <lsb@postel.co.kr>]

Hi, all

I am ready to receive any criticisms on REORDERING.
Any suggestions of improvements or downsides of REORDERING are all welcome.

I expect many feedbacks from non-US and non-European participants and observers.

Thanks.

Soobok Lee
