> This all being said, as a boat captain responsible for the people underwater, I would love a local area network that allows me to pull the plug on a dive, or get some emergency notification. For example “weather is turning, please call the dive” or “I was blown off the wreck, please pick me up”.
In case you are interested, there is a Finnish company called UWIS (short for underwater information systems), that does exactly this [1]. Their system has buoyes that can track the diver units and provide communication channel between on the surface pc and the divers via wifi and sonar network. The system allows two way communication. Tight bandwidth of course as a limiting factor.
Zoowm did some more recent push on this space. Personally felt that the idea of inifinite desktop really made sense. Similarly as in physical world, when you need more space on the table, you spread your stuff on a broader area.
