Re: [External] Re: Request for information - Challenges in routing related to semantic addressing

I can't argue with an effort to define the term "semantic routing".
However, I would be very concerned by an effort to define goals for it 
before we have such a definition.  Depending upon the definition, the 
answer may be that it is a bad idea.

Yours,
Joel
