Hi Brian, FYI I'm planning a permanent(ish) hexayurt in the more temperate (but damp) Pacific Northwest coastal climate. Also 1/2" plywood with wood for edge supports/connectors so would love to collaborate with you in some manner on design details, certainly to stay tuned to how your effort goes (I was not necessarily planning to start in earnest before spring). The twist is that the sheeting I've secured is aluminum clad on both sides - so it's much stiffer than plain plywood (same principal as SIP panels) although quite a bit heavier (about 90 pounds for a 4x8 sheet). My guess is that on balance it will require about the same level of support and could use a similar approach to insulation.
BTW I happen to be in central NH this week through next Monday - Hanover area - so if you are getting rolling that fast and wanted some help please advise.
