We had a similar discussion at the Kesurokai in Germany about the scope of timber framing there. It's not subject to speculation or opinion because the figures are kept and according to Hannes this kind of construction makes up about 0,01 percent of all construction. I believe that the German case represents the high end as well. When the population a species of animal reaches a similar decline we speak of it as extinct so I disagree with both Tim's idea of a resuscitation and Jay's of a continuation. My sense is more of an externally induced life support condition.
