Bitcoin radio network?

[Steve]

I believe this has been mentioned before (it definitely has on IRC), but I'm fascinated by the topic and want to bring it up again...one of the nice properties of the bitcoin protocol is that communications are asynchronous...nodes only need to announce transactions and blocks to anyone willing to listen.  I've never dabbled in HAM radio or anything, but it seems like transactions and blocks would be the perfect thing to broadcast over some sort of radio network as a backup to the internet.
