Key difference, this one has demonstrated it working!
Jokes aside, I'm sure Clinkle had something working in a demo form but obviously the problem is sound as a digital communication medium is terrible outside of specific use cases (air gap attacks?).
re clinkle: i have definitely witnessed it working in person. not that that says anything in particular about clinkle. and yeah, knowing a lot of the people who worked there i definitely feel great delight and kinship with that particular blow up. and i worked at Color (Labs) for a bit, which, in terms of blow ups was like Clinkle before Clinkle, so i feel like i've had front row tickets to two of the best ones from that era! :)

Clinkle is up there in the who's who of blow ups.
