I have for some time thought that we should start deciding on what to
do, but I do not think we are ready to say idna/nameprep.
We have decisions to do before that:


1) Are we going to use UTF-8 only? (and accept that this will force
   many applications to get fixed, that otherwise could wait a long time
   with fixing).
   
   
   
2) If the answer to 1) is No, the an ACE will be nedded.

   The we get: Is the goal to have UTF-8 as nativ format in DNS in
   the future, or are we going to use ACE forever?
     - If we are going for UTF-8 then ACE is a transition mechanism.
       The ACE should then be simple and fast to implement.
     - If we are going for ACE forever, the ACE selected need to
       be compact so that as many characters can be included in
       as few bytes as possible.
       
       
3) If the goal is UTF-8.
   - ACE support should be declared to end at a curtain date, say 2010.
   - The best solution then is to use something like UDNS, which
     supports both the future UTF-8 and the ACE/IDNA backward
     compatibility mechanism.
