where i have wanted SDR most is for wide area digital broadcast of Tor
consensus, for example, along with extended descriptor information,
perhaps over DVB-T bands adopted for the purpose (like the Sweedish
experiments?)

in terms of observability, it may actually be worse to use SDR links
unless they also provide strong authenticity and privacy guarantees at
the physical layer - WirelessWarrior discusses this in talks and
cypherpunks.

an interesting idea, even if not near-term practical :)
