I just want to double-ditto Scott's concerns. (At least in cold regions.)

I saw a frame need major repairs within 10 years, due to condensed vapor on the outside faces of the posts. I blame insufficient vapor retarder detailing, combined with modern insulation.

Foe me, this is a concern with an infill system, since every post represents a penetration of the vapor retarding plane and the conditioned space within the wall. As we know, SIPs need perfect edge-to edge sealing, for the same reason.

I'd think in this case I'd run both strapping/lathe and (taped) vapor barrier continuous right past the inside faces of the posts, since they are concealed anyway. Thus to reduce plaster cracking, also.

Good luck.
