A few thoughts.
--I won't be out when there is a frost, or snow, short of something totally unexpected.
--I live in an area with a ton of bugs where I would want netting. The only issue is how to minimize the weight and still be functional.
--I'm prefer more than just perimeter netting.
--Yes, I would pay for more netting if the concept works.
There wouldn't be any netting to droop in one's face because the only netting would be along the perimeter, and bottom, just like the Zpacks Hexamid.
I would then add some groundsheet inside the tent. Maybe tyvek, maybe cuben. Don't know at this point.
Add my reason here:
There would be significantly less netting (and thus less weight) than using an innernet as the netting on all four sides are completely eliminated. BPWD shows an example of the Luna 4 with a netting door and perimeter netting. In my example, the only additional work is adding the netting to have a full floor of it.
