I don't know much about shortwave radio, but there are some low-power low-bandwidth "modes" that are text-only. I'd love to see a portable/handheld device that implemented a shortwave version of e-mail or instant message chat that would work without any support infrastructure, at least point-to-point. A shortwave Blackberry?? Does anything like that exist?

Thanks,
Steve
