The data is small enough you could receive the stream over Inmarsat or Iridium. And before you rebutt cost, I know exactly how much those carbon mast boats cost.
The other devices (preferably more then one) should be on other boats to be effective out on the oceans. So there is bit of a chicken en egg problem: not very useful if you are the only user.
It would be a project to discuss with a big freight company. One that has already many boats out there anyway. Maybe to get it started and financed.
Never knew of XM weather. But the reception is only in US & Canada so I guess only interesting for coastal areas ? Nevertheless, I wonder where they get their lightning data. Which is US-only according to the website.
