I am a fan of David Rowe's work on codec2 which is a very low-bitrate codec designed for digital voice over HF frequencies.  None of the alternative solutions though have the ubiquitous reach of the mobile phone itself, unless, as Jon suggests, you start including these radios in mobile handset design.  A more ambitious prospect.

Looks like David is building a narrowband modem for Outernet now: http://www.rowetel.com/blog/?p=4538

Speaking of HF, the idea of globally propagating signals is very appealing to me (in a romantic, Nikola Tesla/earth-resonance kind of way). 

I'm aware of the constraints of spectrum, high power and large antennas, but I wonder if there is a practical way for an ultra-narrowband HF uplink to be combined with direct broadcast satellite for an asymmetrical duplex system (like ISPs use to do with dial-up for the uplink back in the 1990s)?
