>prohibitively Yup. According to http://www.groundcontrol.com/IsatHub.htm http://www.groundcontrol.com/IsatHub.htm and http://www.groundcontrol.com/BGAN_rate_plans.htm http://www.groundcontrol.com/BGAN_rate_plans.htm 50mb will cost you around $400. (Just a quick search but when I researched this a little more in depth a few years ago prices weren't too different from that). + the modem which is ~$2000 IIRC. Of course this is if you would buy the data for yourself. Though quiet a few ships have sat internet installed. The data rates are usually pretty low so it's good enough for email but not for surfing bloated websites like Stackoverflow or Google. And then there's the alternative of 3G/4G GSM when you're near the shore.
