Also, as I said, I have a shortwave receiver, and the idea of transmitting data over shortwave is what got my attention. If shortwave, why not other parts of the spectrum? Why not radio itself?
Anyway, I will have to look into this a bit more. As I said in another reply to Andrew, just a few minutes before, I conceive of this as a kind of backup plan for internet access, in emergency situations, for example, or when one finds onself in a remote place without the usual ways of connecting; just to be able to send and receive emails or text, or to use a text-only browser, could be a lifesaver in extreme circumstances.
The key search term you want is "Internet over ham radio". It's feasible, and there are some implementations out there that can carry email, telnet, and other text-based protocols. The issues have more to do with legal limitations on radio spectrum use—most sections of spectrum are pretty specific on what you can do with them.
