Dan,

Cost not withstanding, the challenge with anything space based are the
harms which can come from a number of disparate hazards. Space debris,
small untracked asteroids/meteors, solar flare radiation bursts, laser
disablement (terrorist or military attack), are but a couple which come to
mind early this morning. Lots of eggs in a single basket.

Never the less, satellite distribution is an already known  tool in the
EAS toolbox. The above hazards are simply a calculated risk of employing
such a network. A number of states are now using commercial services
employing geostationary satellite distribution for their statewide
networks recognizing and accepting those hazards.

With the above said and factored, such a network has proven to be useful
in  conditions like the present Louisiana floods where the entire
terrestrial infrastructure is inundated in the flooded areas.

I will also go on to say NPR network is a PEP distribution network which
uses satellite for distribution. That covers about 1000 stations. And I
seem to recall XM/Sirius are also involved...but am unclear as to how.

FEMA needs to get with Cumulus and AP to employ both systems extensive and
disparate satellite equipped station pool for distribution of PEP content
and alerts. Between AP, NPR and Cumulus, that would cover all but a few
stations and remove the delicate terrestrial IoT infrastructure from the
middle of national alert distribution. And offer an element of distributed
risk through diversity of facilities.
