The million dollar carbon fiber sailboats that compete in the Volvo Ocean Race in 2009 used three systems for voice, data, and fax communications. The one that I recall was Thrane & Thrane SAILOR 500 Fleet Broadband. They would shoot HD video with HD cameras and then upload clips via that system from the middle of the ocean. SAILOR 500 Fleet Broadband is a complete system with bandwidth up to 432kbps and allows phone calls to be placed at the same time. I believe the monthly service fee is upwards of $400 a month excluding equipment fees and installation.
