aok, that sounds like a legitimate comment for the NAB to make. Not that their viewpoint should prevail, but it's legitimate to say "Hey, we've got this industry with lots of society's effort invested in it, lots of consumers use our services, you might want to think about that before throwing it all away to set up new services that may or may not pan out". I'm not sure "service preservation" should be a priority, but it's certainly a relevant consideration.
