Awesome project!

This would be fairly great fit for underwater UAV's, or like security camera way out on the edge of property. May be a good idea to post on ardu-sub related discussion forums. I'm not aware of an off the shelf module that's point to point ADSL, almost every modem is intended to yell at a ADSL / ADSL2+ host.

Did you run into any issues with consumer-grade gigabit switches negotiating 10Mbit?

Blue Robotics sells the fathomX exactly for this purpose. I wouldn't be surprised if it uses the same chip set.

That tops out at around 300meters. Ours goes beyond 1km. Still there's is awesome for camera feeds; I love the Blue Robotics hardware, SPEBlox Long is just a different application (more industrial automation focussed)

Any chance you're going to release schematics / open source the design?
