whambasted, you are a gifted inventor who needs a marketer.
re marketing: the video pics don't show enough about the vestibule for me understand how it works or how much space it adds, if any. (I ran it with the sound off.) Give us a still pic or two taken from the vestibule side, maybe one from inside showing the vestibule.
The mini tipi has appealing weight but appears to have minimal useable floor space, especially for those of us in wet country where it is an axiom not to ever let sleeping bag etc. touch a side wall or ceiling.
I LIKE the flat tarp option. There are times when there is NO spot that fits any pre-determined tent footprint. I have designed (though not built) a flat tarp that converts into a partly or fully enclosed floorless shelter.
