Kevlar will not melt.

I could easily see people slinging it around themselves barely checking to see if they were in the harness properly and totally forget to rig it! So...no better than a freefall again. But where would you anchor a jizzilion of these in a highrise? Would there be enough windows/space for everyone on that floor? If there wasn't one for everyone, again issues with panic...people fighting over them, fighting each other to get them on, people running into each other while they are rappelling down? I'm just curious how those sorts of problems will be avoided.

I am assuming it has at least 300 feet or cord ( likely more) and the whole device is a small as it is. Just think how big a similar device that had 300 ft. of PMI pit rope or similar in it would be. I suspect it was a challenge to the designers to come up with a device like that and make it compact . The key to that device I suspect was coming up with the Kevlar cord and winding it up so it will be reasonably compact. We have all carried 300 feet of PMI up a monster hill and know hoe big that bundle is.

That makes sense. Only the high-end clients have any need to survive.
