This may be useful for improving security, especially of CDNs. Binary Transparency seems to be one of the use cases mentioned in the spec[1] - perhaps someday this would be used for an unified scheme for signing application packages/updates, without reinventing the wheel every time.
I'm not sure whether it's comparable, but Chris Squire from Yes spent months "hibernating" in a hotel after a bad trip with homemade acid:
“I’d had lots of good acid trips prior to that. But I made the mistake of trying some acid some friends of mine had homemade. That knocked me back, and I did sort of hibernate in an apartment in Kensington and spent quite a few months — maybe as much as a year — just playing bass.”
This won't work, at least on Chrome. It blocks all cross-domain requests to localhost[1]. Even if the target is used with a domain that resolves to 127.0.0.1, or has CORS completely disabled with "Access-Control-Allow-Origin: *".
Would be nice to have an option for different art pieces on different spaces as well. For example, I use 4 spaces on my primary display and 1 space on the external one and I'd be delighted if I had 5 different art pieces shown.
