What kind of internet link and how fast?

Almost all offshore voice communication is being done via satphones
these days such as Iridium. Price averages about $1.50/min or less
using pre-paid service. The monthly charge can be as low as $35
depending on the plan. While not exactly cheap it is certainly
reasonable enough if you need to keep in touch or have an emergency.
