It is pretty cool, I'll definitely give you that. But I'm not sure there'll ever be an "affordable" version. There's a limited market for this kind of thing and it has to be so overbuilt that I don't see a lot of room for cutting corners.
About the only places I see this working are either some sort of eco-tourism outfit offering travelers "a night in the rainforest canopy", or maybe as a set piece in some zombie movie where a group seeks refuge from an ever gathering horde of zombies. Refuge, that is, until the sullen, good-for-nothing character that everyone hates discovers he still has a few smokes left and accidentally sets fire to his corner of the tent, depositing the survivors into the upstretched arms of the undead.
Man, is it so wrong that I see epic scenes of fighting zombies everywhere I look?
