How about protestors using it to exchange information while avoiding any observable electronic transmission?

I'd be interested to know if it was a good fit for that. What kind of information do you think might be exchanged? (Currently the rate of transfer is relatively slow, but for small-ish amounts of information it could be ok).

...It would be fun to add Diffie-Hellman to the app.
