This can be pretty useful for embedding an iframe with a local service
(I do that for babcom[1]: Decentralized comments over Freenet, sadly still
pretty slow, because I’m using an in-Freenet system for that which
wasn’t optimized for the usecase).

On the downside, companies use the same methods to connect local
services with playback-restrictions (DRM) which aren’t easily doable via
the web alone. Likely this is the reason why it’s still possible, though
I’d wish it were the other way round (possible for the good usages, not
possible for the problematic-but-profitable ones)…
