      Many thanks for the feedback and support on behalf of the ISPs in
      Vietnam.  
      
      I will try to incorporate a summary of the comments below into my 
      presentation at the forthcoming APNIC meeting.
      
      I hope to see you there.
      
      Best wishes,

      > ----------
      > It is proposed that the current size of the minimum allocation should
      > be lowered from a /20 to a /21. It is also proposed that the
      > respective criteria for an initial allocation should be amended such
      > that the LIR must:
      > 
      >     - have used a /23 from their upstream provider or demonstrate an
      >       immediate need for a /23; and
      > 
      >     - demonstrate a detailed plan for use of a /22 within a year;
      > 
      > All other aspects of the policy would remain unchanged.
      > 
      > 
      > 6 Implementation
