Nick -
About your question on CIRs in LEED:
I think LEED 2009 reviewers aren't bound by any previous CIRs - http://www.gbci.org/Certification/Resources/cirs.aspx
However, the rumors continue that this could be changing, with "LEED Interpretations" - http://www.leeduser.com/topic/usgbc-offer-precedent-setting-leed-interpretations-along-cirs
