> IETF-sponsored experimental proposals likely to see broad 
> deployment contain no mechanisms that would have deleterious 
> effects on the overall system. The Area Directors intend, 
> therefore, to request that the experimental proposals be 
> reviewed by a focused technology directorate. This review

> the working group chairs and area advisor have concluded that 
> such energy would be better spent on gathering deployment experience.
