There is also some work in the IETF on the more general problem of distributing early warning messages: <http://tools.ietf.org/wg/atoca> Right now, they're taking a pretty layer-7 approach (distributing CAP in SIP messages), but part of their charter is figuring out how this application relates to things like iPAWS, CMAS, 3GPP PWS, etc. So they will likely end up looking at some layer-2/3 aspects of the problem as well. --Richard On Thu, Dec 2, 2010 at 4:42 PM, Jay Ashworth <jra@baylink.com> wrote:

What would be really awesome (unless I've missed it) is Internet access to the emergency broadcast system and local weather services; all easily handled with multicast.
Ah, something I know something about for a change. :-)
In fact, there's some work in progress on this topic, Jack; FEMA is working on replacing the EAS -- which itself replaced EBS, and earlier, Conelrad -- with a new system called iPAWS: The Integrated Public Alert and Warning System.
At the moment, they're working on the "replace the EAS backbone" part of it, which work is about a year behind schedule, and everyone wants an extension, but there are other useful places to apply some effort. I'm a designer, not a coder, so I've been piddling around in the part I'm good at; thinking about design.
Some of the results are here:

and

and I invite off-list email from anyone who has suggestions to toss in the pot.
