Lana and her husband just completed their 30 day cruise running a BEOS node. Here's the route data, color coded for when they were in international waters.
Note the route color change as we left international waters.
So we pretty much demonstrated that at most latitudes we've got satellite connectivity to the BEOS network.
Currently a BEOS node with 5 peers consumes about 2.6 kbps down and less than 1 kbps up. This is easily handled by Royal Caribbean's high speed 10 mbps network.
Stay tuned when I check it out in the Atlantic Bermuda Triangle on my cruise with Bytemaster and family next month.
