The folks at http://www.cyclonecom.com/ have apparently hooked up a
system to allow high speed internet and television from the same dish on
an RV that's currently touring the US. See
http://www.fieldtripusa.net/ for details. The newspaper article that
told this story indicated the product worked good at automatically
acquiring satellites. It wouldn't work on a moving boat, but could
probably be set out on a dock at a marina. I sure do think there could
be a market for such a product...
