The antenna product would be pretty sweet, though it doesn't get around the fact that satellite data transfer is still pretty expensive^ comparatively speaking, though maybe getting a lot more people on board with it would bring the price down. But it'd be even better for the larger ship-borne satellite receivers already out there which right now use a bunch of expensive gears and circuitry to be able to target satellites (and often break), seems like it would solve making those systems less complex as well as make a good consumer product.
^I base this on personal experience shopping for and paying for broadband data on a ship I worked on, things may have changed significantly since that time though.
