It is trivially easy to have a dedicated UDP port to receive broadcast packets for such purposes, as "through streaming services" is not the requirement.
Though, sadly, 911/udp is taken, and by someone who may not exist anymore. Who owns the <1024 post list these days, IANA?
As streaming services are often offered from distant places including foreign locations, generations of emergency alert packets *MUST* be responsibility of *LOCAL* ISPs.
A problem is that home routers may filter the broadcast packets from ISPs, but the routers may be upgraded or some device to snoop the alert packets may be placed between ISPs and the routers.
Yup; it's messy, and in many many different ways. Won't be a snapshot rollout. Not a bad idea, though, if implemented correctly; time to dig out my notes, I guess. Cheers, -- jra -- Jay R.
