They are now pulling on the same end of the rope.  Dan Smith and John Swearingen of this list have helped adjust the non-structural language.  I also received input from Andy Mueller of this list for a renewed Northeastern US perspective.

This includes clay, soil-cement, lime, cement-lime, cement, and gypsum plasters.  For the last four plaster types I reference long-standing sections of the International Building Code or ASTM Standards (with a some adjustments for use of these plasters on strawbale walls).  Wherever possible (and wherever not inappropriate for strawbale) it is best for this proposed strawbale section to be in sync with the IBC and its referenced standards.

>> Would anyone from this list (with good clay plaster experience) like to be part of a mini task force on this issue?  If people let me know by end of Wednesday January 18, the individual or small group (no more than 3?) would have through Monday January 23 to propose language.  I could send you what I have currently off-list or you could choose to be blind to it.  Looking at existing language regarding plasters in the IBC or in ASTM standards (if you have access to these), is not mandatory but might be useful.
