Um.

The existing EAS system already does point 1, I believe - and uses raw 
audio or PCM wav files - no MP3 compressed file can outperform wav or 
raw audio, and can play them back into the automation's external input, 
if desired - at least some endecs have this capability.  The "other 
languages" may be desirable - or moot, as states adopt "official 
language" statutes that prohibit using any language except English for 
official communications.  And yes, it's already happening.  It's being 
disguised as a cost-cutting measure in some cases - eliminating the cost 
of multi-lingual signage and brochures, for example -  but it's coming.

Point 2 a.) Why?  2 b) would be a better option, I'd think - and some 
NOAA radios already do this, as well as 2 c)... and the SAME encoding is 
supposed to be able to define locales; but hasn't been fully implemented 
- how would "GPS" improve that for my bedside radio?  Dashboard radios, 
maybe...  and the "FM Chip in the cell phone" might use such a feature, 
but that would be implemented in the receiver - select enhanced SAME 
based on locale.  No need for CAP there, either.

Point 3 goes back to TV vs Radio... And hearing impaired folks generally 
don't listen to radio very much in the first place.

Just to show I'm not being close-minded - the CAP text message, in 
addition to feeding normal character generators for TV, Cable, and 
"intelligent highway" signs could also feed the closed-caption 
generators - but again, that's the *visual*, not *aural* component.

The flaw in the system that *needs* to be addressed is the alerting 
transport, not the protocol.
