The direction is that:

- The IESG is OK if the WG wants system ports if they have some 
  reasonable argument to request so. The stronger the argument,
  the better.  But a reasonable argument is OK.
- I think the arguments I have seen pro and against sofar make me
  tend to agree with selecting <1024. They seem at least reasonable.
  (I am in the air right now, so I can only comment as to what I have seen
  up till now).
- I have seen arguments for using ports above 1024 too. 
  they are OK but I do not find them as convincing (yet) as the ones
  in favor fo <1024.
- I have not seen arguments that point out a fatal problem if we
  assign below 1024.
- I find it important that people who have implented (or are implementing)
  or those who plan to deploy now or within a year are speaking up. Their
  view counts heavily as far as I am concerned.

Hope this helps,
Bert (speaking as AD)
