Storing data in music | ETH Zurich
Embedding small data in music, preferably with lots of dominant notes in 9.1-10KHz range, so pop music. Might be useful for data smuggling in the open, if you are within 24m and can stand 400 baud...

So Ubuntu modemmanager arbitrarily probes new serial devices with AT commands to detect if they are modems or not, screwing other devices that don't expect that at connection start.

On Covert Acoustical Mesh Networks in Air
Oh hey, who has a computing device with both a mic and speaker? Everyone with a smartphone apparently. How useful this could be in say, a revolution/riot scenario. Interesting that the network protocols build on work for submarine communications...

Kumu Networks
Using self interference tricks to cancel out noise to effectively create a single carrier full duplex radio. There was a SatCom company (ComTech called it Carrier-in-Carrier) doing this in in L-band, but this company wants to do it in LTE/ISM bands, which requires 5 orders of magnitude more cancelling signal.

New Measurement Device Helps Monitor Power Consumption via Power Line -- Tech-On!
So somebody is finally getting around to the problem of monitoring non-smart appliances and getting the data to building management systems without having to install new networking lines (while avoiding wireless like ZigBee due to limited spectrum) by using an inline PLC modem to send data to a management station/controller. Smart to use the inline device as a switchable sensor/master. Now if only somebody like Intel or Atmel or TI could make a nice single chip hybrid sensor/PLC modem for both retrofit and new build devices, things could really change.

Revolutionary Communications System Promises New Generation of Untethered, Undersea Vehicles
200m range isn't much, but if you set up a mesh network of these near an underwater platform you could potentially do autonomous survey/monitoring runs. The other thought being dropping a long tether-like cable with these optical modems at 100m intervals with a small ROV at the bottom to drag around the end of the cable, operating like a mobile accesspoint for other ROV's and UUV's/AUV's. The military application would be a sonar buoy accesspoint connecting to a sonar module that drops below local thermoclines to see under them.

A nice little system using LED lighting to also transmit data, combined with a custom small form factor retroreflector/receiver (not much bigger than existing IRda sensors). They are also doing PLC and DC PLC work, so that the overhead lamp assembly contains not only the LED and transmitter encoding circuits, but also a PLC modem for transmitting data over the power supply circuit so you can retrofit into exisitng lighting systems without running new data cables.
